how many miles to a tank of gas?
<answer> 20 gallons tank holds 10,000 miles. <context> Let's say your vehicle's tank holds 20 gallons and the odometer shows 10,000 miles. Next time you get gas, your vehicle takes in six new gallons to get to F for full. Your odometer shows 10,120 miles. Subtract the 10,000 miles you started with from the 10,120 miles it shows now. That means you went 120 miles on six gallons of gas. Divide the 120 by 6, and you'll come up with 20.
