a train running at the speed of 300 km / hr crosses a pole in 15 seconds . what is the length of the train ?
"speed = ( 300 * 5 / 18 ) m / sec = ( 250 / 3 ) m / sec length of the train = ( speed x time ) = ( 250 / 3 * 15 ) m = 1250 m . answer : b"
multiply(divide(multiply(300, const_1000), const_3600), 15)
