A train 150 m long is running with a speed of 68 km/h. In what time will it pass a man who is running at 8 km/ h in the same direction in which the train is going?

Correct Answer: 9 sec

Explanation:

Relative speed = 68-8 = 60 km/hr = 60 X 5 / 18 m/s = 50/3 m/s


Total distance = 150 m


Time taken to pass a man running in same direction = 150 X 3/50 = 9 seconds
