A 250 m long train is running at a speed of 55 Km/hr. It crossed a platform of length 520 m in ? (Its a Previously asked on SSC 2012 exam) (*without a train question it is impossible to conduct an exam, I think you got, what I mean)	Options
A) 40.4 sec	B) 50.4 sec	C) 40.5 sec	D) 50.5 sec	E) 52.0 sec
Speed = 55 Km/hr   (to convert km/hr in to M/s)   = 55 x 5/18 M/s   Distance = 250 m + 520 m ( If questions is about train crossing a post you need to consider only the length of Train, )   = 770 m   Time = Distance / Speed   = 770 x 18 / (5 x 55)   = 50.4 sec   Answer: OPTION 50.4 sec
