Answer 1

Input data

18 mile river trip

$249

Ratio?

Procedure

R = ratio

`\begin{gathered} R=(249)/(18) \\ R=13.8333\text{ \$/mile} \end{gathered}`

13.8 dollars per mile

To calculate how many miles I can travel for one dollar we will use the following expression

`M=(1)/(R)=(1)/(13.8)=0.072\text{ miles}`

You can travel 0.072 miles with one dollar.
