Question
A train takes 16 seconds to pass a stationary boy. The
same train requires 38 seconds to traverse a platform measuring 495 meters in length. Determine the length of the train.Solution
Let, length of train be ‘x’ m Speed of train = x/16 m/s So, (x + 495)/38 = x/16 16x + 7920 = 38x 22x = 7920 x = 360
