Solution:
The distance D, travelled is;
[tex]\text{Distance}=speed\times gallon[/tex]Where;
[tex]\begin{gathered} \text{Speed}=22\text{mpg} \\ \text{Distance}=1,684\text{mile} \\ \text{gallon}=\frac{1684}{22} \\ \text{gallon}=76.55 \end{gathered}[/tex]The total gas that would be used for the trip is 76.55gallon.
But, the cost of gas is about $3.42 per gallon.
Hence, the approximate driving cost of the trip would be;
