Final answer:
To find the miles per gallon your car gets, divide the total distance traveled by the total gallons of gas used.
Step-by-step explanation:
To find the miles per gallon your car gets, you need to calculate the total distance traveled divided by the total gallons of gas used. Here's how:
- First, calculate the total distance traveled by multiplying the one-way distance to Clarksville by 2 (since you traveled there and back): 99 miles x 2 = 198 miles.
- Next, subtract the amount of gas added from the total amount of gas used: 9 gallons - 7 gallons = 2 gallons.
- Finally, divide the total distance traveled by the total gallons of gas used to find the miles per gallon: 198 miles ÷ 2 gallons = 99 miles per gallon.
Therefore, your car gets 99 miles per gallon.
