In order to compare which driver used fewer gas per mile, let's divide the amount of gas used by the total miles ran of each driver:

[tex]\begin{gathered} \text{driver 1:} \\ \frac{3\frac{3}{4}}{45}=\frac{\frac{15}{4}}{45}=\frac{1}{12}\text{ gallon per mile} \\ \\ \text{driver 2:} \\ \frac{5\frac{2}{3}}{85}=\frac{\frac{17}{3}}{85}=\frac{1}{15}\text{gallon per mile} \end{gathered}[/tex]

So the driver that used fewer gas per mile is the second one.
