A train 360 m long can cross an electric pole in 30 sec and then find the speed of the train?
Choose the correct choice from the following answers
A) 88 kmph B) 43 kmph C) 72 kmph D) 16 kmph E) 18 kmph

Rationale: "length = speed * time speed = l / t s = 360 / 30 s = 12 m / sec speed = 12 * 18 / 5 ( to convert m / sec in to kmph multiply by 18 / 5 ) speed = 43 kmph answer : b"
Answer: B
