d = rt     r = d/t = 20/45 mi/min
20/45 mi/min 60 min/hr = 1200/45 mi/hr
= 26.667 mi/hr

As you reminded us at the end of the question:

         Speed  =  (distance) / (time)

                     =  (20 miles) / (60 minutes)

                     =    (1/3) mile/minute

To convert to the units you asked for . . .

                 (1/3 mile/minute) · (60 minutes/hour)

             =    (1/3 · 60)  (mile · minute) / (minute · hour)

             =            20  mile/hour .
