Question
A 240 m long train crosses a platform twice its length
in 3 min. Find the speed of the train.Solution
Speed of train = (Length of train + Length of Platform)/Required time Length of train = 240 m Crossing time of platform = 3 × 60 = 180 sec Length of platform = 240 × 2 = 480 m Let the speed of train be x. Speed of train = (240 + 480)/180 ⇒  x = 4 m/s
