Aldo drove to the mountains last weekend. There was heavy traffic on the way there, and the trip took 8 hours. When Aldo drove home, there was no traffic and the trip only took 5 hours. If his average rate was 21 miles per hour faster on the trip home, how far away does Aldo live from the mountains? Do not do any rounding.

    8x = 5 (x+21)

    8x = 5x + 105

    3x = 105

    x = 105 / 3

    x = 35

    8 x 35 = 280 miles away
