Sarah wants to buy a new car and is deciding between two models. She has convinced both car dealerships to allow her to test drive each car for hours as long as she returns with a full tank of gas. In order to test the performance of both vehicles, she kept track of her velocity during her test drive every half hour. The results of her test drives are shown below.

Sarah finds that both cars performed exceptionally well and she would be very happy with either one. She decided to make her final decision based on the gas mileage of each model. Her test drive of the Coronado Speedster used gallons of gas and her test drive of the D.O. Sensation used gallons. Which car should she choose?

Find the area of both graphs to find total miles traveled for each car.
