Problem: a train is 435 meter long is running at a speed of 45 km / hour . in what time will it pass a bridge of 140 meter length
Rationale: "explanation : speed = 45 km / hr = 45 * ( 5 / 18 ) m / sec = 25 / 2 m / sec total distance = 435 + 140 = 575 meter time = distance / speed = 575 ∗ 2 / 25 = 46 seconds option c"
annotated_formula: divide(add(435, 140), divide(multiply(45, const_1000), const_3600))
