A train 1500 m long can cross an electric pole in 50 sec and then find the speed of the train? Choose the correct option:  A) 106  B) 107  C) 108  D) 109  E) 110

Rationale: "length = speed * time speed = l / t s = 1500 / 50 s = 30 m / sec speed = 30 * 18 / 5 ( to convert m / sec in to kmph multiply by 18 / 5 ) speed = 108 kmph answer : c"
Answer: C
