A train 165 m long is running at the speed of 60 km/hr. Find the time taken to pass a man who is running at a speed of 6 km/hr in the same direction as that of the train?
11 s
Given,
Speed of man (S2) = 6 km/hr
Speed of the train (S1) = 60 km/hr
The man and the train are moving in the same direction,so the relative speed = (S1−S2)=(60−6)=54 km/hr
Converting it to m/s,
54×518=15 m/s
Length of train = 165 m
Time taken by the train to pass the man is DistanceRelative speed=16515=11s
