due to construction , the speed limit along an 8 - 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 ?
"old time in minutes to cross 8 miles stretch = 8 * 60 / 55 = 8 * 12 / 11 = 8.72 new time in minutes to cross 8 miles stretch = 8 * 60 / 35 = 8 * 12 / 7 = 13.71 time difference = 4.99 ans : a"
max(multiply(subtract(add(55, 8), const_1), subtract(divide(8, 35), divide(8, 55))), const_4)
