Question
A train crosses two platforms of length 1000 m and 600 m
in 80 seconds and 60 seconds, respectively. What is the length of the train?Solution
Let the length of the train be x m. As we know, Speed = (x + 1000)/80 ---(1) Speed = (x + 600)/60 ---(2) From equation (1) and equation (2) (x + 1000)/80 = (x + 600)/60 3 (x + 1000) = 4 (x + 600) 3x + 3000 = 4x + 2400 4x-3x = 3000-2400 x = 600 The length of the train is 600 m.
