Problem: a train is 360 meter long is running at a speed of 45 km / hour . in what time will it pass a bridge of 240 meter length ?
Rationale: "speed = 45 km / hr = 45 * ( 5 / 18 ) m / sec = 25 / 2 m / sec total distance = 360 + 240 = 600 meter time = distance / speed = 600 * ( 2 / 25 ) = 48 seconds answer : e"
annotated_formula: divide(add(360, 240), divide(multiply(45, const_1000), const_3600))
