a train running at the speed of 40 km / hr crosses a pole in 27 seconds . what is the length of the train ?
"speed = ( 40 * 5 / 18 ) m / sec = ( 100 / 9 ) m / sec length of the train = ( speed x time ) = ( 100 / 9 * 29 ) m = 300 m . answer : b"
multiply(divide(multiply(40, const_1000), const_3600), 27)
