! during the last five races, jim's race car used an average of 15 gallons of gas per race. if his race car used a total of 51 gallons of gas during the first three races, what was the total number gallons of gas used during the last two races?

The answer could be 34.

Step-by-step explanation: Since he used an average of 15 gallons per race we can divide 51 by 3 which gives us 17 and since it's average it doesn't have to be exact. Then we multiply by 17*2 which give us 34 and that's our answer. Im sorry if I'm incorrect I tried my best! Hope this helps!
