Question
A 360 m long train crosses a platform twice its length
in 3 min. Find the speed of the train. Section 1Solution
Speed of train = (Length of train + Length of Platform)/Required time Length of train = 360 m Crossing time of platform = 3 × 60 = 180 sec Length of platform = 360 × 2 = 720 m Let the speed of train be x. Speed of train = (360 + 720)/180 ⇒ x = 6 m/s
