A train 520 m long can cross an electric pole in 20 sec and then find the speed of the train?  Options:
A) 88 kmph  B) 94 kmph  C) 72 kmph  D) 16 kmph  E) 18 kmph

Rationale: "length = speed * time speed = l / t s = 520 / 20 s = 26 m / sec speed = 26 * 18 / 5 ( to convert m / sec in to kmph multiply by 18 / 5 ) speed = 94 kmph answer : b"
Answer: B
