A 300 meter long train crosses a platform in 36 seconds while it crosses a signal pole in 18 seconds. What is the length of the platform?
Pick.
A) 300m
B) 278m
C) 350m
D) 228m
E) 282m
Speed = [300 / 18] m/sec = 50/3 m/sec.   Let the length of the platform be x meters.   Then, x + 300 / 36   = 50/3   3(x + 300)   = 1800 è x   = 300m.   300mnswer:300m
