Question

To find out how far the truck can drive with 7 gallons of gasoline, we first need to determine the truck's miles per gallon (MPG).

The truck drives 150 miles using 15 gallons of gasoline. We can calculate the MPG as follows:

\[
\text{MPG} = \frac{\text{miles driven}}{\text{gallons used}} = \frac{150 \text{ miles}}{15 \text{ gallons}} = 10 \text{ miles per gallon}
\]

Now that we know the truck gets 10 miles per gallon, we can find out how far it can drive with 7 gallons:

\[
\text{Distance with 7 gallons} = \text{MPG} \times \text{gallons} = 10 \text{ miles per gallon} \times 7 \text{ gallons} = 70 \text{ miles}
\]

Therefore, the truck could drive **70 miles** with 7 gallons of gasoline.

The correct response is:
**70 miles**
