Question
A train, measuring 450 meters in length and traveling at
a speed of 35 meters per second, takes 20 seconds to pass a platform. If another train, traveling at a speed of 20 meters per second, crosses the same platform in 25 seconds, determine the length of the second train.Solution
Let assume the length of the platform is 'x' metres and length of train 'B' is 'y' metres ATQ; (450 + x) = (20 X 35) Or, 450 + x = 700 Or, x = 250 And, (y + 250) = 25 X 20 Or, y + 250 = 500 Or, y = 250 So, length of train 'B' = 250 metres. Hence, option d.
