Problem: a train running at the speed of 110 km / hr crosses a pole in 9 sec . what is the length of the train ?
Rationale: "speed = 110 * 5 / 18 = 275 / 9 m / sec length of the train = speed * time = 275 / 9 * 9 = 275 m answer : b"
annotated_formula: multiply(divide(multiply(110, const_1000), const_3600), 9)
