Write and solve an equation of ratios:

15 min              3 racks
----------      =     -------------
      x                  36 racks

Solving this for x:  3x = (15)(36)  =>  x = 180 minutes.

convert this into hours:     180 min        1 hr
                                         ------------ * -------------- = 3 hrs (answer)
                                               1              60 min
