Julia had to make 6 cakes for the party. Each cake takes 12 minutes to mix and needs 9 more minutes to bake than mix. Then it takes 6 more minutes to cool and decorate than to bake. How many hours will it take to make all 6 cakes? Give me reasons, before answering the question
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. So the final answer is 6.
