Final answer:
Karen got approximately 13.18 miles per gallon on her trip in her 2002 Toyota Corolla.
Step-by-step explanation:
To calculate the miles per gallon for Karen's trip, we first need to find out how many gallons of gas she used. Her 2002 Toyota Corolla has a 13.2-gallon gas tank, and she filled it up after traveling 340 miles. So, the number of gallons used is 340 divided by 13.2, which is approximately 25.76 gallons.
Next, we divide the number of miles traveled (340) by the number of gallons used (25.76) to calculate the miles per gallon. Therefore, Karen got approximately 13.18 miles per gallon on her trip.
