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 (x+300)/39=50/3 3(x+300)=50x39 3x+900=1950 3x=1950-900 3x=1050 x=1050/3 x=350m so length of platform is 350m
