To find out how many miles per gallon Sara can drive, we need to calculate her fuel efficiency. We can do this by dividing the total miles driven by the total gallons of gas used.
-
Calculate miles per gallon (MPG): \[ \text{MPG} = \frac{\text{Total miles}}{\text{Total gallons}} = \frac{72 \text{ miles}}{3.2 \text{ gallons}} = 22.5 \text{ miles per gallon} \]
-
Calculate how many miles she can drive on 13.3 gallons of gas: Now that we know her MPG, we can multiply that by the amount of gas she will use: \[ \text{Miles} = \text{MPG} \times \text{Gallons} = 22.5 \text{ miles per gallon} \times 13.3 \text{ gallons} = 299.25 \text{ miles} \]
Therefore, Sara can drive approximately 299.25 miles on 13.3 gallons of gas.
