Baking Time!

Let's see if you can solve these baking questions:

If it takes 1 hour to make 50 cookies, how many hours would it take to make 250 cookies?
If it takes 45 minutes to make 25 brownies, how many minutes would it take to make 100 brownies? Can you convert this to hours?


NCTM Standard: Measurement (time)
NCTM Standard: Number and Operations
