Final answer:
The unit rate of miles per gallon for the car is 42, calculated by dividing the number of miles traveled, 525, by the gallons of gas used, 12.5.
Step-by-step explanation:
To calculate the unit rate in miles per gallon for the car, we simply divide the total number of miles traveled by the total gallons of gas used. In this case, the car travels 525 miles on 12.5 gallons of gas. Using division to find the unit rate, we get:
Unit rate (miles per gallon) = Total miles traveled ÷ Total gallons of gas used
Unit rate (miles per gallon) = 525 miles ÷ 12.5 gallons
Unit rate (miles per gallon) = 42 miles per gallon
Therefore, the car gets 42 miles per gallon.
