It takes 4 cooks 4 hours to bake 4 cakes. Assuming no change of rate, how many hours will it take 8 cooks to bake 8 cakes?

No cake takes 4 hours in the oven to bake. Therefore, each cake takes one hour in the oven. Since you have 8 cakes, it will take 8 hours. Please correct me if I'm wrong other members on 2.0calc.

4 cooks

4 hours

4 cakes

 

 

4 cakes / (4 cooks X 4 hours)  =   4 cakes / 16 cook-hours = 1 /4  cake/cook-hours

 

8 cakes /  1/4 cake/cook-hour   = 32 cook hours

32 cook-hour / 8 cooks = 4 hours
