Suppose you walk 2 miles in 35 minutes. Solve the proportion you found in the previous exercise.

Remember, Haity, that the rest of us do not have an illustration of the previous exercise.  You'll have to share it.

 2 miles
------------ = 0.057 miles per minute, or  0.057 miles     5280 ft
 35 min                                                  ----------------- * -----------------
                                                                    1 minute     1 mile

                                                          or  301 feet per minute.
