A train 150 m long can cross an electric pole in 3 sec and then find the speed of the train?	Choose the correct option
A) 180
B) 120
C) 72
D) 27
E) 28

Rationale: "length = speed * time speed = l / t s = 150 / 3 s = 50 m / sec speed = 50 * 18 / 5 ( to convert m / sec in to kmph multiply by 18 / 5 ) speed = 180 kmph answer : a"
Answer: A
