Problem: a train 300 m long is running at a speed of 45 km / hr . in what time will it pass a bridge 150 m long ?
Rationale: "speed = 45 * 5 / 18 = 25 / 2 m / sec total distance covered = 300 + 150 = 450 m required time = 450 * 2 / 25 = 36 sec answer : option b"
annotated_formula: divide(300, multiply(subtract(45, 150), const_0_2778))
