A 200 m long train is running at a speed of 100 km/h. In how much time will it pass a man standing near the railway line?
Answer & explanation
Correct answer: option 3
Speed = 100 km/h
100 km/h = 100 × \(\frac{5}{18}\) m/sec = \(\frac{500}{18}\) m/sec
Distance to be covered is = 200 m
Time taken = \(\frac{200 × 18}{500}\) = 7.2 sec
So , Time taken by train to cross a men is 7.2 sec
