Question

A train running at 25km/he takes 18 sec to pass a platform.Next,it takes 12 sec to pass a man walking at 5km/hr in the opposite direction.Find the sum of length of train and that of platform.

Answer 1

125 meters length of platform+train

Answer 2

Answer:

When it jumps platform

Train speed 25km/h

Time 18 sec

5x25/18 = L/18

L = 125

When train crosses a man

5x25+5/18 = L/12

L = 100

So, 125-100 = 25meter is your answer.
