A train 200 m long can cross an electric pole in 5 sec and then find the speed of the train?	Options:
A) 114
B) 124
C) 134
D) 144
E) 154

Rationale: "length = speed * time speed = l / t s = 200 / 5 s = 40 m / sec speed = 40 * 18 / 5 ( to convert m / sec in to kmph multiply by 18 / 5 ) speed = 144 kmph answer : d"
Answer: D
