conversations.value: It takes 12 + 9 =21 minutes to bake each cake.
  It takes 21 + 6 = 27 minutes to cool and decorate each cake.
  Therefore, it takes a total of 12 + 21 + 27 = 60 minutes to make one cake.
  Thus, it takes 60/60 = 1 hour to bake one cake.
  So, it will take 1 x 6 = 6 hours to bake all 6 cakes.
