You just drove your car 500 miles and used 20 gallons of gas. You know that the gas tank on your car holds 15 1/2 gallons of gas. What is the most number of miles you can drive on one tank of gas

387 1/2 miles

Step-by-step explanation:

From the question, we know that 20 gallons can be used for 500 miles. Therefore, the gallons of gas per mile will be:

= 500/20

= 25 gallons per mile.

The number of miles that a 15 1/2 gallons will use will be:

= 25 × 15 1/2

= 387 1/2 miles
