8.5 minutes per mile is equivalent to 

17 minutes
----------------
  2 miles

and the reciprocal of that is


2 miles
-----------
17 min

Now multiply 26.2 miles by 

17 min                                   (17 min)* (26.2 mi)
------------ ,    obtaining         ---------------------------
 2 miles                                           2 mi

This simplifies to (17)(26.2)/2 minutes = 222.7 minutes, 

or

222.7 minutes        1 hr
-------------------- * ------------ = 3.7 hours
          1                  60 min
