To find the unit rate of miles per gallon, you can divide the total number of miles by the total number of gallons.

Given:
- Miles traveled = 420 miles
- Gallons used = 10 gallons

The calculation is as follows:

\[
\text{Miles per gallon} = \frac{\text{Miles}}{\text{Gallons}} = \frac{420 \text{ miles}}{10 \text{ gallons}} = 42 \text{ miles per gallon}
\]

Thus, the unit rate is **42 miles per gallon**.
