Question

PLEASE HELP!!!!!!!!!!!!!!! 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?

Answer 1

Answer: 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!
