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
