Answer 1

14 miles per gallons.

Explanation:

We have been given that after filling a gas tank the odometer read 19,874.5. After the next filling it read 20,105.5. It took 16.5 gal to fill the tank. We are asked to find the mileage.

`\text{Mileage}=\frac{\text{Total distance traveled}}{\text{Total fuel consumed}}`

`\text{Mileage}=\frac{\text{20,105.5 miles}-\text{19,874.5 miles}}{\text{16.5 gallons}}`

`\text{Mileage}=\frac{\text{231 miles}}{\text{16.5 gallons}}`

`\text{Mileage}=14\frac{\text{miles}}{\text{gallon}}`

Therefore, the driver get a mileage of 14 miles per gallons.
