Question
A train of 250 metres is moving at a speed of 90 km/h.
It completely crosses a platform in 45 seconds. What is the platform’s length?Solution
ATQ,
Let the length of the platform be ‘x’ metres
Speed of the train = 90 × (5/18) = 25 m/s
ATQ,
(x + 250) = 25 × 45
Or, (x + 250) = 1125
Or, x = 1125 - 250
Or, x = 875
Therefore, the length of the platform = 875 metres
