Question 60

A 360 m longtrain running at a uniform speed, crosses a platform in 55 seconds and a man standing on the platform in 24 seconds. What is the length (in metre) of the platform?

Solution

The train with length 360 m passes by a man standing at the platform in 24 seconds .The speed of the train is

V= 360/24= 15 m/s

Let the length of the platform be L

(L+ 360)/ 55 = 15

L+360= 15*55

L+360=825

L= 825-360

L= 465 m.
