Question
A train running at 90 km/h crosses an electric pole in
18 seconds and a platform in 55 seconds. What is the length of the platform?Solution
Let the length of the platform be P meters. 90 km/h = 90 ÷ 18/5 = 25 m/sec Hence, the length of the train = 25 × 18 = 450 meters. According to the question, 25 × 55 = (450 + P)  1375 = 450 + P   P= 925 The length of the platform is 925 m.
