You know that Bob runs 10 miles in 79 minutes.
Let be "x" the number of miles Bob runs per minute.
You can set up the following proportion using the data provided in the exercise:
[tex]\frac{10}{79}=\frac{x}{1}[/tex]Solve for "x", in order to find its value:
[tex]\frac{10}{79}=x[/tex][tex]x\approx0.13[/tex]Hence, the answer is:
[tex]\approx0.13\text{ }miles\text{ }per\text{ }minute[/tex]
