Problem: due to construction , the speed limit along an 10 - mile section of highway is reduced from 55 miles per hour to 35 miles per hour . approximately how many minutes more will it take to travel along this section of highway at the new speed limit than it would have taken at the old speed limit ?
Rationale: "old time in minutes to cross 10 miles stretch = 10 * 60 / 55 = 10 * 12 / 11 = 10.9 new time in minutes to cross 10 miles stretch = 10 * 60 / 35 = 10 * 12 / 7 = 17.14 time difference = 6.24 ans : a"
annotated_formula: max(multiply(subtract(add(55, 10), const_1), subtract(divide(10, 35), divide(10, 55))), const_4)
