Question
A train crosses a platform in 36 seconds and a pole in
24 seconds. If the length of the train is 300 meters, what is the length of the platform?Solution
Speed of the train = Length of train / Time to cross the pole = 300 / 24 = 12.5 m/s. Length of the platform = Speed × (Time for platform - Time for pole) = 12.5 × (36 - 24) = 150 m. Correct Option: c
