The rate at which body cover distance is given by speed.
The formual for the speed is,
[tex]s=\frac{d}{t}[/tex]For the given question, distance is d=34 miles and time is t=4/5 hours.
Substitute the value in the formula to obtain the speed of Camden.
[tex]\begin{gathered} s=\frac{34\text{ miles}}{\frac{4}{5}\text{ hr}} \\ =\frac{34\cdot5}{4}\text{ miles/hr} \\ =\frac{85}{2}\text{ miles/hr} \end{gathered}[/tex]So the speed at which camden cover distance is 85/2 miles per hour.
