a train is 360 meter long is running at a speed of 54 km / hour . in what time will it pass a bridge of 140 meter length ?
"speed = 54 km / hr = 54 * ( 5 / 18 ) m / sec = 15 m / sec total distance = 360 + 140 = 500 meter time = distance / speed = 500 * ( 1 / 15 ) = 33.33 seconds answer : b"
divide(add(360, 140), divide(multiply(54, const_1000), const_3600))
