a train 360 m long can cross an electric pole in 30 sec and then find the speed of the train ?
"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"
divide(divide(360, const_1000), divide(30, const_3600))
