Answer :
Final answer:
The unit rate of gasoline usage by the car is calculated by dividing the total miles driven (100.5 miles) by the total gallons used (3.75 gallons), which results in a rate of 26.8 miles per gallon.
Explanation:
The way to find the unit rate, or the rate at which the car is using gasoline, is to divide the total distance traveled by the total gallons of gasoline used. In this case, we have 100.5 miles driven and 3.75 gallons of gas used. Therefore, the unit rate calculation would be:
100.5 miles ÷ 3.75 gallons = 26.8 miles per gallon
So, as a decimal, the rate of gasoline usage by the car is 26.8 miles per gallon.
