A 300 meter long train crosses a platform in 48 seconds while it crosses a signal pole in 18 seconds. What is the length of the platform?  Choose the most appropriate option.
A) 500 B) 289 C) 350 D) 882 E) 281
Speed = [300 / 18] m/sec = 50/3 m/sec.   Let the length of the platform be x meters.   Then, x + 300 / 48 = 50/3   3(x + 300) = 2400 è x = 500m.   500nswer: 500
