So we want to mess to estimate the annual gala gasoline usage by all of the automobile member out of automobile owners in America. So rather in the United States. So in the United States there are approximately 300,000,000 people so three times 10 to the eighth people. And then we're going to say that for every two people there are one auto one automobile. So essentially 50% of that population has a car, so one automobile divided by rather per every two people. And then we're going to say that Ah, if you have an automobile, you drive approximately 12,000 miles per year. So 12,000 miles for every auto automobile divided by one year. And then we're going to multiply this by the gas efficiency of an average car. We can say that the average car gallant or one gallon will take you approximately 20 miles, and so the total gasoline usage would be approximately. We can say weaken round one times 10 to the 11th gallons per year. That is the end of the solution. Thank you for watching
