Step-by-step explanation:
Since the question implies his truck travels at a constant distance per gallon, we can set up the following proportion to find how much father his truck can go.

If this question is as simple as it seems all you would have to do is subtract. If he is down 96 feet then goes up 49 feet you would do 96-49.
The answer is 47 feet.
