Question
A train 180 m long is running at a speed of 54 km/h. It passes a platform in 20 seconds. What is the length of the platform?
Solution
ATQ, Speed = 54 km/h Convert to m/s: 54 × (5/18) = 15 m/s Time to cross platform = 20 s Distance covered in 20 s = speed × time = 15 × 20 = 300 m This distance = length of train + length of platform 300 = 180 + platform length Platform length = 300 − 180 = 120 m
