Final answer:
To find the gas usage rate in miles per gallon, divide the total miles traveled by the total gallons of gas used. In this case, with 64 miles traveled using 2 gallons of gas, the car has a gas mileage of 32 miles per gallon.
Step-by-step explanation:
To calculate the car's gas mileage or rate of gas consumption in miles per gallon (mpg), we should follow this formula:
Miles per gallon (mpg) = Total miles traveled / Total gallons of gas used
Using the information provided:
Total miles traveled = 64 miles
Total gallons of gas used = 2 gallons
Plugging these values into the formula:
mpg = 64 miles / 2 gallons
mpg = 32 miles per gallon
Therefore, the car uses gas at a rate of 32 miles per gallon.
