A 300 metre long train crosses a platform in 39 seconds while it crosses a signal pole in 18 seconds. What is the length of the platform?
speed = 300/18 = 50/3 m/s
Let the length of the platform be x metres.
50/3 = ( x + 300) / 39
x = 350 m
Speed = (300/18)m/sec=50/3 m/sec
So Let the length of the platform be x metres
so length of platform is 350m
