Answer 1

To solve this problem it is necessary to use proportions. In this case, take x as the number of miles that you could drive on 65 gallons of gas.

It means that x is to 65 as 510 is to 20:

`\begin{gathered} (x)/(65)=(510)/(20) \\ x=(510)/(20)\cdot65 \\ x=1657.5 \end{gathered}`

It means that you could drive 1657.5 miles on 65 gallons of gas.
