s=(d)/(t)

The equation above is the formula of the speed (s) in terms of the distance (d) and the time (t).

For the distance 132 mi

With a speed of 8 miles per hour it takes the next hours:


\begin{gathered} \\ \text{Solve t:} \\ s\cdot t=d \\ t=(d)/(s) \\ \\ t=(132mi)/(8(mi)/(h))=16.5h \end{gathered}

With a speed of 12 miles per hour it takes the next hours:


t=(132mi)/(12(mi)/(h))=11h

Then, the possible number of hours that take to the kayaker to travel 132 miles is between 11 and 16.5
