Problem: steve traveled the first 2 hours of his journey at 35 mph and the remaining 3 hours of his journey at 80 mph . what is his average speed for the entire journey ?
Rationale: "distance traveled in 2 hours = 2 * 35 = 70 m distance traveled in 3 hours = 3 * 80 = 240 m total distance covered = 240 + 70 = 310 m total time = 2 + 3 = 5 h hence avg speed = total distance covered / total time taken = 310 / 5 = 62 mph answer : d"
annotated_formula: add(divide(add(multiply(80, 3), multiply(35, 2)), add(3, 2)), subtract(divide(const_100, 3), const_0_33))
