Final answer:
To find the fuel efficiency, divide the distance traveled by the amount of gas used. Karen's 2002 Toyota Corolla got approximately 25.76 miles per gallon on her trip.
Step-by-step explanation:
To calculate the fuel efficiency of Karen's 2002 Toyota Corolla, we use the formula:
Miles per gallon (mpg) = Miles traveled / Gallons of gas used
Karen traveled 340 miles and filled up a 13.2-gallon gas tank. So, her car's fuel efficiency is:
Mpg = 340 miles / 13.2 gallons
We can carry out the division to find the answer.
Mpg = 25.76
Therefore, Karen's 2002 Toyota Corolla got approximately 25.76 miles per gallon on her trip.
