It takes 30 minutes to make pizza dough and another 30 minutes in the oven for the pizza to cook. If one batch of pizza dough can make 3 pizzas but the oven can only fit 2 pizzas at a time, how many hours would it take for Camilla to finish making 12 pizzas?
Camilla needs 12/3 = <T>divide(12, 3)=4.0 batches of pizza dough.
4 batches of pizza would require 30 x 4 = <T>multiply(4, 30)=120 minutes
Camilla needs to bake the pizzas 12/2 = <T>divide(12, 2)=6.0 times
6 times in the oven would take 30 x 6 =<T>multiply(6, 30)=180 minutes
Altogether, it would take 120 + 180 = <T>add(120, 180)=300 minutes to finish making 12 pizzas
300 minutes is 300/60 = <T>divide(300, 60)=5.0 hours
