Considering the population of U.S. being 323,000,000 we will have the statement:
3 people .................................... 2 cars
323,000,000 people .................. x cars
=>
cars.
Next we will found out the miles driven in one year by all the cars:
215,333,333 * 10000 = 2,153,333,330,000 miles/ year.
2,153,333,330,000 : 365 = 5,899,543,378 miles/ day.
5,899,543,378 : 20 = 294,977,168 gallons.
