due to construction , the speed limit along an 12 - 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 ?
"12 / 35 - 12 / 55 = 12 / 5 * ( 11 - 7 ) / 77 = 12 / 5 * 4 / 77 * 60 min = 12 * 12 * 4 / 77 = 576 / 77 ~ 7.4 answer - d"
max(multiply(subtract(add(55, 12), const_1), subtract(divide(12, 35), divide(12, 55))), const_4)
