দেওয়া হয়েছে:

স্টেশন P থেকে স্টেশন Q পর্যন্ত গতি: 70 কিমি/ঘন্টা

স্টেশন Q থেকে স্টেশন P পর্যন্ত গতি: 90 কিমি/ঘন্টা

সূত্র:

গড় গতি = 2xy/x + y

সমাধান:

গড় গতি =(2 × 70 × 90)/70 + 90 = 78.75 কিমি/ঘন্টা

অতএব, সমগ্র যাত্রায় বাসের গড় গতিবেগ 78.75 কিমি/ঘন্টা

Q8.Five jumbled up sentences, related to a topic, are given below. Four of them can be put together to form a coherent paragraph.

Machine learning models are prone to learning human - like biases from the training data that feeds these algorithms. 2. Hate speech detection is part of the on - going effort against oppressive and abusive language on social media. 3. The current automatic detection models miss out on something vital: context. 4. It uses complex algorithms to flag racist or violent speech faster and better than human beings alone. 5.
