Gasoline takes up a lot of space—oil tankers that deliver the raw material for gasoline are HUGE. We don’t see the gasoline if we fill up a tank, but the tanks are big, because cars use a lot of gasoline. A typical U.S. “car” (whatever it is we drive—averaging somewhere between a Prius and a Hummer, and including a lot of pickup trucks and minivans) gets about 20 miles per gallon, and drives about 12,000 miles per year. So, how many gallons of gas per year does a typical car burn? The equation should look like miles/year divided by miles/gallon to get gallons/year.单项选择题
