Question

A train having a length of 400 m, travelling at a speed of 15 m/s, crosses a platform in one minute. What is the length of the platform?

Answer 1

Let the length of platform be x metre .

Distance of Train = 400 metre

Speed = 15 m/sec

Time = 1 minute = 60 second

Total Distance = x + 400 metre

D = St

x + 400 = 15 * 60

x + 400 = 750

x = 750 - 400

x = 350 metre

So, Length of platform is 350 m.
