Answer: Cam can bake 192 cakes in 40 mins
Explanation:
Since Cam can bake 144 cakes in 30 mins, it is appropriate to assume that dividing this amount by 30 would give the total amount of cakes she can bake in 1 min. 144 divided by 30 gives the sum of 4.8 cakes. Now that we know how many cakes can bake per min, we must multiply the total by 40 because that is the question we are trying to answer. 40 multiplied by 4.8 gives a product of 192 cakes.
