aaron will jog from home at 6 miles per hour and then walk back home by the same route at 12 miles per hour . how many miles from home can aaron jog so that he spends a total of 3 hours jogging and walking ?
"xyt / ( x + y ) x = 6 , y = 12 t = 3 6 * 12 * 3 / 6 + 12 = 12 answer : a"
divide(multiply(multiply(6, 12), 3), multiply(6, 12))
