Latest Speed Time and Distance MCQ Objective Questions

Speed Time and Distance Question 1:

Nikita travels by a motorboat down the river to her school and back. With the speed of the river remaining unchanged, if she doubles the speed of her motorboat, her total travel time decreases by 75%. What is the ratio of the original speed of the motorboat to the speed of the river?

  1. \(\sqrt7:2\)
  2. \(\sqrt6:\sqrt2\)
  3. 1:2
  4. 3:2

Answer (Detailed Solution Below)

Option 1 : \(\sqrt7:2\)

Speed Time and Distance Question 1 Detailed Solution

- www.amglogisticsinc.net

Let us take the speed of the boat and river to be \( b \) and \( x \) respectively and let the distance be \( d \).

As per the condition in the question, \( \frac{d}{x + b} \) is the normal time taken. \( \frac{d}{2x + b} \) is the special time taken i.e. if the speed gets doubled.

Since the time gets reduced by 75%, \( \frac{1}{4} \left[ \frac{d}{x + b} + \frac{d}{x - b} \right] = \left[ \frac{d}{2x + b} + \frac{d}{2x - b} \right] \)

We have to find the ratio of the speed of the motor boat to the speed of the river = \( \frac{x}{b} \)

Let us divide throughout by \( b \) and assume \( \frac{x}{b} = k \)

\( \frac{1}{k + 1} + \frac{1}{k - 1} = 4\left[\frac{1}{2k + 1} + \frac{1}{2k - 1}\right] \)

Solving for \( k \), we get: \( 2k \times (k^2 - 1) = 16k \times \left(k^2 - 1\right) \)

Hence, the ratio of the original speed of the motor boat to the speed of the river is equal to: \( \frac{\sqrt{7}}{2} \)

Speed Time and Distance Question 2:

 Train ‘P’, running with a speed of 144 km/h, crosses a pole in 17 seconds. If the time taken by train ‘P’ to cross train ‘Q’ running with a speed of 72 km/h and coming from the opposite direction is 22.8 seconds, then find the length of train 'Q'.

  1. 688 meters
  2. 660 meters
  3. 448 meters
  4. 620 meters
  5. None of these

Answer (Detailed Solution Below)

Option 1 : 688 meters

Speed Time and Distance Question 2 Detailed Solution

Train P crosses a pole in 17 seconds. The length of Train P is equal to the distance it covers in 17 seconds.

Speed of Train P = 144 km/h

Convert speed to m/s:

144 × 5/18 = 40 m/s

Length of Train P = Speed × Time

Length of Train P = 40 × 17 = 680 m

Train P and Train Q are moving in opposite directions. Their relative speed is the sum of their individual speeds.

Speed of Train P = 144 km/h = 40 m/s

Speed of Train Q = 72 km/h

Convert speed to m/s:

72 × 5/18 = 20 m/s

Relative speed = 40 + 20 = 60 m/s 

Train P takes 22.8 seconds to cross Train Q. The combined length of the two trains is equal to the distance covered at the relative speed in 22.8 seconds.

Combined Length = Relative Speed × Time = 60 × 22.8 = 1368 m

The combined length of Trains P and Q is 1368 m, and the length of Train P is 680 m. Therefore, the length of Train Q is:

Length of Train Q = Combined Length Length of Train P = 1368 - 680 = 688 m

Thus, the length of Train Q is 688 meters.

Speed Time and Distance Question 3:

Time taken by a boat is two hour less than when the boat cover 72 km downstream than time taken by the boat to cover 72 km upstream. If speed of stream is 3 km/hr. Find the upstream speed? 

  1. 21
  2. 9
  3. 15
  4. 12
  5. 18

Answer (Detailed Solution Below)

Option 4 : 12

Speed Time and Distance Question 3 Detailed Solution

Let speed of boat is x km /hr.

so, ATQ, [72 / (x - 3) ] - [ 72 / (x + 3)] 2

or, x2 - 9 = 36 × 6 = 216

or, x2 = 225

or, x = 15

so, speed of boat is 15 km /hr.

upstream speed is 15 - 3 = 12 km /hr 

Speed Time and Distance Question 4:

A Train travel 420 km at p km/hr and remaining 420 km at 140 km/hr. Total time taken by train to cover the whole distance is 6  hour 30 minutes. Find the time taken by train to cover 600 km at p km/hr?

  1. 4.5
  2. 7.5
  3. 5
  4. 6
  5. 5.5

Answer (Detailed Solution Below)

Option 3 : 5

Speed Time and Distance Question 4 Detailed Solution

Train cover 420 km distance at 140 km /hr.

so, Time taken = 420 /140 = 3 hour.

Time travel by train at p km/hr speed is 6.5 - 3 = 3.5

Distance travel at p km/hr is 420 km.

so, p = 420 / 3.5 = 120 km /hr

so, time taken to cover 600 km distance at p km /hr is  = 600 / 120 = 5 hour.

Speed Time and Distance Question 5:

When Shreya increases her speed from 20 km/h to 25 km/h, she takes one hour less than the usual time to cover a certain distance. What is the usual distance covered by her?

  1. 125 km
  2. 100 km
  3. 120 km
  4. 80 km

Answer (Detailed Solution Below)

Option 2 : 100 km

Speed Time and Distance Question 5 Detailed Solution

- www.amglogisticsinc.net

Here, the distance traveled by Shreya is constant in both the cases.

So, \(20 \times t = 25 \times (t - 1) = D\)

\( \Rightarrow 20t = 25t - 25\)

\( \Rightarrow 5t = 25\)

\( \Rightarrow t = 5 \text{ hrs. So, Distance travelled} = 20 \times 5 = 100 \text{ Km.}\)

Given

Length of first train (L1) = 400 m

Length of second train (L2) = 300 m

Speed of second train (S2) = 60 km/hr

Time taken to cross each other (T) = 15 s

Concept:

Relative speed when two objects move in opposite directions is the sum of their speeds.

Calculations:

Let the speed of the first train = x km/hr

Total length = 300 + 400

Time = 15 sec

According to the question:

700/15 = (60 + x) × 5/18

28 × 6 = 60 + x

x = 108 km/hr.

Therefore, the speed of the longer train is 108 km per hour.

Given:

Speed is 60 km per hour,

Train passed through a 1.5 km long tunnel in two minutes

Formula used:

Distance = Speed × Time

Calculation:

Let the length of the train be L

According to the question,

Total distance = 1500 m + L

Speed = 60(5/18)

⇒ 50/3 m/sec

Time = 2 × 60 = 120 sec

⇒ 1500 + L = (50/3)× 120

⇒ L = 2000 - 1500

⇒ L = 500 m

∴ The length of the train is 500 m.

Given:

Total track length = 1200 m

Speed of A = 2 m/s ; speed of B = 4 m/s

Speed of C = 6 m/s

Formula used:

Distance = relative speed × time

Calculation:

Relative speed of A and B = (4 - 2) = 2 m/s

Relative speed of B and C = (6 + 4) = 10 m/s

Relative speed of A and C = (6 + 2) = 8 m/s

Time taken by A and B = 1200/2 = 600 sec

Time taken by B and C = 1200/10 = 120 sec

Time taken by A and C  = 1200/8 = 150 sec

A, B and C will meet at = L.C.M {600,120, 150} = 600 sec = 600/60 = 10 minutes

∴ The correct answer is 10 minutes.

In a 1500 m race, Anil beats Bakul by 150 m and in the same race Bakul beats Charles by 75 m. By what distance does Anil beat Charles?

  1. 217.50 m
  2. 200.15 m
  3. 293.50 m
  4. 313.75 m

Answer (Detailed Solution Below)

Option 1 : 217.50 m

Speed Time and Distance Question 9 Detailed Solution

Download Solution PDF

Given:

In a 1500 m race, Anil beats Bakul by 150 m and in the same race Bakul beats Charles by 75 m.

Concept used:

Time × Speed = Distance

Calculation:

According to the question,

Anil goes 1500m while Bakul goes (1500 - 150) i.e. 1350m.

Ratio of speed of Anil and Bakul = 1500 : 1350 = 10 : 9 = 200 : 180

According to the question,

Bakul goes 1500m while Charlie goes (1500 - 75) i.e. 1425m.

Ratio of speed of Bakul and Charlie = 1500 : 1425 = 20 : 19 = 180 : 171

So, the ratio of the speeds of Anil, Bakul and Charlie = 200 : 180 : 171

Let the speeds of Anil, Bakul and Charlie be 200k, 180k and 171k m/s respectively.

Time taken by Anil to finish the race = 1500/200k = 7.5/k seconds

Now, Anil beats Charlie by = (200 - 171)k ×7.5/k = 217.5m

∴ Anil beat Charlie by 217.5m.

Shortcut Trick

In a 1500 m race, Anil beats Bakul by 150 m

When Anil completes the race, Bakul covered (1500 - 150) = 1350 m

In a 1500 m race Charles is 75 m behind Bakul

So, in 1350 m race Charles is 75/1500 × 1350 = 67.5 m behind Bakul

So, Charles is (67.5 + 150) = 217.5 m behind from Anil in 1500 m race

∴ Anil beat Charlie by 217.5m.

  1. 66.67 m
  2. 65 m
  3. 65.33 m
  4. 66 m

Answer (Detailed Solution Below)

Option 1 : 66.67 m

Speed Time and Distance Question 11 Detailed Solution

Download Solution PDF

Given:

Geeta runs 5/2 times as fast as Babita 

Geeta gives a lead of 40 m to Babita 

Formula Used:

Distance = Speed × Time 

Calculation:

Let the speed of Babita be 2x

⇒ Speed of Geeta = (5/2) × 2x = 5x

Let the distance covered by Geeta be y meters

⇒ Distance covered by Babita = (y - 40) meters

As time is constant, distance is directly proportional to speed 

\(\frac{2x}{5x}\) = \(\frac{y-40}{y}\)

⇒ 2y = 5y - 200 

⇒ y = 200/3 = 66.67m 

∴ The distance from the starting point where both of them will meet is 66.67 m

Speed Time and Distance Question 12 Detailed Solution

Download Solution PDF

Concept used:

Speed × time = distance

Calculation:

In the 1st 20 min the thief cover distance = 4 m,

20 min in hour = 20/60 hour

Let's assume that the speed of security guard = x m/hr, where x > 12

According to the question,

⇒ (x - 12) × 20/60 = 4

⇒ x - 12 = 12

⇒ x = 24

∴ The correct answer is 24 m/h

A boat goes 20 km upstream and 44 km downstream in 8 hours. In 5 hours, it goes 15 km upstream and 22 km downstream. Determine the speed of the boat in still water.

  1. 6 km/h
  2. 10 km/h
  3. 8 km/h
  4. 7 km/h

Answer (Detailed Solution Below)

Option 3 : 8 km/h

Speed Time and Distance Question 13 Detailed Solution

Download Solution PDF

Concept used:

If upstream speed = U and downstream speed = D, then speed of boat = (U + D)/2

Calculation:

According to the question,

20/U + 44/D = 8  … (i)

15/U + 22/D = 5  … (ii)

Multiply by 2 the equation (ii) then subtract from 1 we get

20/U + 44/D = 8

30/U + 44/D = 10

- 10/U = - 2

⇒ U = 5 km/hr

Putting the value in equation (i), we get D = 11

So, the speed of boat = (U + D)/2 = (5 + 11)/2 = 8 km/hr

∴ The correct answer is 8 km/hr

Two trains, one 152.5 m long and the other 157.5 m long, coming from opposite directions crossed each other in 9.3 seconds. The combined speed of the two trains every hour would then be:

  1. 130 km/hr
  2. 125 km/hr
  3. 115 km/hr
  4. 120 km/hr

Answer (Detailed Solution Below)

Option 4 : 120 km/hr

Speed Time and Distance Question 14 Detailed Solution

Download Solution PDF

Given:-

Train1= 152.5m

Train2= 157.5m

Time = 9.3 sec

Calculation:-

⇒ Total distance to be covered = total length of both the trains

= 152. 5 + 157.5

= 310 m

Total time taken = 9.3 sec

Speed = distance/time

= (310/9.3) m/sec

= (310/9.3) × (18/5)

= 120 km/hr

∴ The combined speed of the two trains every hour would then be 120 km/hr.

Alternate Method When two trains are moving in opposite direction-

Let the speed of ine is 'v' and the second is 'u'

∴ Combined speed = v + u

Total distance = 152.5 + 157.5

= 310 m

∴ Combined speed = Total distance/total time

⇒ (v + u) = 310/9.3

⇒ (v + u) = 33.33 m/s

⇒ (v + u) = 33.33 × (18/5)

⇒ (v + u) = 120 km/hr
