Q: 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?
A: 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 is 10.
Question: Emberly takes her mornings walks every day. If each walk takes her 1 hour covering 4 miles, and she didn't walk for 4 days in March, calculate the total number of miles she's walked.
Answer: In March, she walked for 31 - 4 = 27 days. If she walks for an hour a day, the total number of hours she'll walk in March is 27 days * 1 hour a day = 27 hours. If each walk is 4 miles, the number of miles she walked in March is 27 * 4 = 108 miles. The answer is 108.
[Question]Barbie and Bruno have a pile of 144 coconuts that they need to move from one side of their yard to the other side. Barbie can carry 4 coconuts at a time, while Bruno can carry 8 coconuts at a time. If they make trips together carrying their maximum number of coconuts each time, how many trips together would they need to make to move all of the coconuts?

[Question]Josh works 8 hours a day, 5 days a week, 4 weeks a month. Carl is an intern and works 2 hours less than Josh every day. Josh gets $9 an hour and Carl, half that. How much does the company pay for the 2 together in one month?
[Answer]
Josh works 8 hours / day * 5 days / week * 4 weeks / month = 160 hours a month. He earns 160 hours / month * $9 / month = $1440 per month. Carl works less because he is an intern: 6 hours / day * 5 days / week * 4 weeks / month = 120 hours per month. Carl earns 120 hours * $4.5 / hour = $540 per month. The company pays for the 2 together: $1440 + $540 = $1980. The answer is 1980.
