Answer 1

Input data

246 milles

82 gallons

18 miles?

Procedure

First, let's calculate the ratio of miles per gasoline

`\begin{gathered} r=\frac{246\text{ milles}}{82\text{ gallons}} \\ r=3\text{ milles per gallon} \end{gathered}`

Now for 18 miles

`g=\frac{18\text{ milles}}{3\text{ milles per gallon }}=6\text{ gallons }`

The answer would be 6 gallons of gasoline
