Car goes 420miles on a 10gallon tank. What is unit rate of miles per gallon?

1 answer

To find the unit rate of miles per gallon, you can use the formula:

\[ \text{Unit Rate} = \frac{\text{Total Miles}}{\text{Total Gallons}} \]

In this case, the car goes 420 miles on a 10-gallon tank. So, you would calculate it as follows:

\[ \text{Unit Rate} = \frac{420 \text{ miles}}{10 \text{ gallons}} = 42 \text{ miles per gallon} \]

Therefore, the unit rate is 42 miles per gallon.
