A driver drove 90 miles and used 4 gallons of gasoline. What is the vehicle's consumption rate in miles per gallon?

1 answer

To find the consumption rate in miles per gallon, you can use the following formula:

\[ \text{Miles per gallon} = \frac{\text{Total miles driven}}{\text{Total gallons used}} \]

In this case, the driver drove 90 miles and used 4 gallons of gasoline. Plugging in these values:

\[ \text{Miles per gallon} = \frac{90 \text{ miles}}{4 \text{ gallons}} = 22.5 \text{ miles per gallon} \]

Thus, the vehicle's consumption rate is 22.5 miles per gallon.
