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?
Select
A) 300  B) 266  C) 230  D) 288  E) 271
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.   300nswer: 300
