Answer 1

Given:

The table shows the number of gallons used to reach the distance by each car.

To find the car that had the highest number of miles per gallon:

Let us find the number of miles per gallon for each car.

For a car A,

`\begin{gathered} \frac{Total\text{ miles}}{Number\text{ of gallons}}=(106)/(5) \\ =21.2\text{ miles per gallon} \end{gathered}`

For a car B,

`\begin{gathered} \frac{Total\text{ miles}}{Number\text{ of gallons}}=(204)/(10) \\ =20.4\text{ miles per gallon} \end{gathered}`

For a car C,

`\begin{gathered} \frac{Total\text{ miles}}{Number\text{ of gallons}}=(298)/(15) \\ =19.87\text{ miles per gallon} \end{gathered}`

For a car D,

`\begin{gathered} \frac{Total\text{ miles}}{Number\text{ of gallons}}=(392)/(20) \\ =19.6\text{ miles per gallon} \end{gathered}`

Therefore, car A has the highest number of miles per gallon.
