If you travel 80 miles on .4 gallons of gas then you travel 500 miles using   
$$500\div80=6.25$$   so the trip is 6.25 times as long as the chicago trip. To get the total amount of gas$$6.25*.4=2.5$$This means you are getting 200 miles to the gallon. The trip of 500 miles took 2.5 gallons in your highly efficient automobile.
