a train is 360 meter long is running at a speed of 45 km / hour . in what time will it pass a bridge of 160 meter length ?
"speed = 45 km / hr = 45 * ( 5 / 18 ) m / sec = 25 / 2 m / sec total distance = 360 + 160 = 520 meter time = distance / speed = 520 * ( 2 / 25 ) = 41.6 seconds answer : b"
divide(add(360, 160), divide(multiply(45, const_1000), const_3600))
