1-175.

TEST DRIVE

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.

Coronado Speedster

First quadrant, x axis labeled time, hours, scaled from 0 to 4, y axis labeled velocity, mph, scaled from 0 to 70, with continuous, vertical & horizontal, segments, starting at (0, comma 20), going right & turning at the following points: up at (0.5, comma 20), right at (0.5, comma 40), up at (1.5, comma 40), right at (1.5, comma 70), down at (2, comma 70), right at (2, comma 60), down at (3, comma 60), right at (3, comma 30), down at (4, comma 30), ending at (4, comma 0).

D.O. Sensation

First quadrant, x axis labeled time, hours, scaled from 0 to 4, y axis labeled velocity, mph, scaled from 0 to 70, with continuous, vertical & horizontal, segments, starting at (0, comma 60), going right & turning at the following points: down at (1, comma 60), right at (1, comma 40), up at (1.5, comma 40), right at (1.5, comma 70), down at (2.5, comma 70), right at (2.5, comma 50), down at (3, comma 50), right at (3, comma 30), down at (4, comma 30), ending at (4, comma 0).

Sarah finds that both cars performed exceptionally well and she will be very happy with either one. She decides 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.
