a train is 360 meter long is running at a speed of 56 km / hour . in what time will it pass a bridge of 140 meter length .
"explanation : speed = 56 km / hr = 56 * ( 5 / 18 ) m / sec = 140 / 9 m / sec total distance = 360 + 140 = 500 meter time = distance / speed = 500 / 140 / 9 = 32.14 seconds answer : d"
divide(add(360, 140), divide(multiply(56, const_1000), const_3600))
