Question

If we consider only the cost of gasoline, how much does it cost ( in dollars) to drive each mile ? Round to the nearest cent.

Answer 1

Given:

The cost of gasoline, c=$2.20/gallon.

The car gets x=26 miles per gallon.

The cost to drive each mile if gasoline costs $2.20/gallon is

`\begin{gathered} T=(c)/(x) \\ =\frac{\frac{2.20\text{ dollars}}{1\text{ gallon}}}{\frac{26\text{ miles}}{1\text{ gallon}}} \\ =\frac{2.20\text{ dollars}}{1\text{ gallon}}*\frac{1\text{ gallon}}{26\text{ miles}} \\ =0.08 \end{gathered}`

Therefore, the two fractions for obtaining the solution is,

`\begin{gathered} \frac{2.20\text{ dollars}}{1\text{ gallon}} \\ \frac{1\text{ gallon}}{26\text{ miles}} \end{gathered}`

The cost in dollars to drive each mile is $0.08 per mile (rounded to nearest cent).
