Set up the equation of two ratios:  

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

Solve this for x:  3x =540; x = 180 minutes, or 3 hours

For 1 rack of buns it takes 5 mins, Therefore you multiply both the number of buns and minutes it take to make 1 rack. 1*36 and 5*36.

Your answer would be 180 mins to make 36 racks of buns
