Question
A train crosses a pole in 18 seconds and crosses a
platform 270 m long in 36 seconds. What is the speed of the train?Solution
Let the length of the train be x m. Then speed = x/18 m/s While crossing the platform: Distance covered = x + 270 So, (x + 270)/36 = x/18 18(x + 270) = 36x 18x + 4860 = 36x 18x = 4860 x = 270 Speed = 270/18 = 15 m/s Convert into km/h: 15 x 18/5 = 54 km/h
