Question

How long will a train 330m long travelling at 40km/h take to cross a platform 110m long? How long will it take to pass a man sitting on the platform?

Answer 1

length of train = 330 m
length of platform = 110m
total distance = 330+110 = 440 m
speed = 40 km/h
= 40 x 5 / 18
=25/9 m /sec
time = distance / speed
= 440 x 9 / 25
= ........
