A warehouse worker loads a cart with 14 boxes. The boxes have an average weight of 24 pounds. The worker picks up a new box and

At first, the warehouse worker loads a cart with 14 boxes and the boxes have an average weight of 24 pounds. The total weight of the boxes will be:

Allen has already run 3 hours and will run x amount more to finish. This is 3+x. He must finish under or less than 5.5 hours. So 3 + x < 5.5. You solve and find x < 2.5.
