Question

A train having a length of 240 meters passes a post in 24 seconds. How long will it take to pass a platform having a length of 650 meters?

Answer 1

Explanation:

Length of a train = 240m

Time to pass the post =24s

speed of train = length of train / time to pass

240m/24s =10m/s

if the train pass a platform having length 650m

speed =10m/s

time = length of train / speed

so, 650m/10m/s = 65s
