the mpg on a car is 23 city 32 highway so how much gas does this car use?

To calculate how much gas this car uses, we need to first determine the average mileage based on the city and highway MPGs.

Average MPG = (City MPG + Highway MPG) / 2
Average MPG = (23 + 32) / 2
Average MPG = 55 / 2
Average MPG = 27.5

This means that the car averages 27.5 miles per gallon.

To calculate how much gas the car uses for a certain distance, you would divide the distance by the average MPG.

For example, if you drive 275 miles:

Gas used = Distance / Average MPG
Gas used = 275 / 27.5
Gas used = 10 gallons

So, for a 275 mile trip, this car would use 10 gallons of gas.
