The machine is advertised as being able to dig 36-foot trenches in 40 minutes:

Since it moves at a constant rate:


\begin{gathered} (36)/(40)=0.9,\text{ }(58.5)/(65)=0.9 \\ 0.9\text{ fe}e\text{t each minute} \\ \text{Let x be the time in minutes} \\ \text{Let y be trench lenght in f}eet \\ y=0.9x \end{gathered}

The unit rate of the situation is 0.9 feet per min.
