Question

A man is walking at speed of 5 km/h when a train passes by him.if the speed of the train is 55 km/h and it's length is 125 m how much time will the train take to pass by him if they travel in the same direction and opposite direction

Answer 1

in same direction speed = 55-5 = 50km/h = 50*5/18 = 125/9 m/s

in opposite direction = 55+5 = 60km/h = 60*5/18 = 50/3 m/s

T1(same direction) = 125*9/125 = 9 second

T2( opposite direction) = 125*3/50 = 7.5 second
