Question

Greta made sugar cookies to share with her friends. She spent 45 minutes making the dough and 50 minutes baking the cookies. Then, she spent 45 minutes decorating the cookies with icing and sprinkles. It was 11:40 A.M. when Greta finally finished all of the cookies. What time did Greta start making the cookies

Answer 1

Answer: 10:00 A.M.

Step-by-step explanation:

To determine what time Greta started making the cookies, we need to add up the time she spent on each step.

First, Greta spent 45 minutes making the dough. Then, she spent 50 minutes baking the cookies. Finally, she spent 45 minutes decorating the cookies.

So, the total time Greta spent on making the cookies is 45 + 50 + 45 = 140 minutes.

We know that Greta finished making the cookies at 11:40 A.M.

To find the time Greta started making the cookies, we need to subtract 140 minutes from 11:40 A.M.

Let's do the calculation:

11:40 A.M. - 140 minutes = 10:00 A.M.

Therefore, Greta started making the cookies at 10:00 A.M.

Hope this helps.

Answer 2

9:20 A.M.

Step-by-step explanation:

If you subtract the times from the end time, you end with 9:20 AM, so she began at 9:20 am.
