From the given information, we can establish the following rule of three:


\begin{gathered} 65\text{ miles ------ 100 \%} \\ 26\text{ miles ------- x} \end{gathered}

where x denotes the unknown percentage. then, by cross-multiplying the above number, we have


x*65\text{ miles=26miles}*100\text{ \%}

Then, by dividing both sides by 65 miles, we get


\begin{gathered} x=\frac{26\text{ miles }*\text{ 100 \%}}{65\text{ miles}} \\ x=40 \end{gathered}

Therefore, the answer is 40 %
