Answer:
D. A travels 90 miles more
Explanation:
The graph tells you Car A travels 140 miles on 5 gallons of gas. (There is a point marked there on the graph.)
The table tells you Car B travels 99 miles on 4.5 gallons of gas. When that is multiplied by 5/4.5 = 10/9 to get the equivalent for 5 gallons, we see that Car B could travel 10/9 × 99 = 110 miles on 5 gallons of gas.
__
Already on 5 gallons of gas, Car A has traveled 30 miles farther. The only sensible answer choice is ...
D. Car A travelled 90 miles more than Car B [when 15 gallons are used].
