[Question]Gretchen read that you should spend 10 minutes walking for every 90 minutes you spend sitting. If Gretchen spends 6 hours working at her desk, how long will she spend walking?
[Answer]First find the total number of minutes Gretchen spends sitting at her desk: 6 hours * 60 minutes / hour = 360 minutes. Then divide this amount by 90 minutes to find how many walking breaks Gretchen takes: 360 minutes / 90 minutes / break = 4 breaks. Then multiply the number of breaks by the length of each break to find how long Gretchen spends walking: 4 breaks * 10 minutes / break = 40 minutes. The answer is 40.

Question: Peggy fell off her bike and skinned her knees. She needed two bandages on her left knee and three bandages on her right knee. If the box of bandages had 8 less than two dozen bandages before Peggy skinned her knees, how many bandages were left in the box after Peggy finished putting bandages on her knees?
Answer:
Two dozen is 12 * 2 = 24. Eight less than two dozen bandages is 24 - 8 = 16 bandages. She needed two bandages on her left knee and three bandages on her right knee for a total of 2 + 3 = 5 bandages. Therefore, after Peggy finished putting bandages on her knees there were 16 - 5 = 11 bandages remaining in the box. The answer is 11.
