Question

If it takes Kathy 2 hours to bake 20 cupcakes, then at that rate, how many cupcakes could be made in 16 hours?

Answer 1

The answer is 160

Explanation:

If it takes 2 hours to bake 20 cupcakes, then the rate is:

20 cupcakes in 120 minutes

Which is equal to 1 cupcake in 6 minutes

Therefore, in 16 hours, or in 16*60=960 minutes, the number of cupcakes that could be made can be found using proportion:

Let's denote the number of cupcakes that could be made in 960 minutes as 'x'

Then:

1 cupcake - 6 minutes

x cupcakes - 960 minutes

Find x: x=(960 * 1)/6=160 cupcakes

Thus, the answer is 160

Answer 2

The answer to this question would be 160 cupcakes in 16 hours
