It took John 16 minutes to cook 8 eggs. How long would it take to cook 15 such eggs?

30 minutes

Step-by-step explanation:

First, you need to find the amount of time it takes to cook one egg. To do this, you do 16/8 to get 2 minutes per egg. Then, since you need to cook 15 eggs, you do 15 times 2 to find the total amount of time to cook. You should get 30.
