Liz roasts 2 16 pounds turkeys every Thanksgiving. She can only roast them 1 at a time because she has a small oven. She roasts each turkey for 15 minutes per pound. If dinner is served at 6:00 pm what is the latest time she can start roasting the turkeys? Let's be accurate as possible.
She bakes a turkey for 15 minutes a pound and the turkey is 16 pounds so it takes 15 * 16 = 240 minutes. She has 2 turkeys to roast and one turkey takes 240 minutes to cook so 2 turkeys will take 2 * 240 = 480 minutes. There are 60 minutes in an hour and these turkeys will take 480 minutes to cook so that's 480 / 60 = 8 hours. In military time, 6:00 pm is 18:00 hours (12 hours + 6 hours) and it takes 8 hours to cook the turkeys so the latest she can start is 18 - 8 = 10:00 am.
The answer: 10.
