The Miami Central Hotel has 420 rooms. Every day, the housekeepers clean any room that was occupied the night before. If a guest is checking out of the hotel, the housekeepers give the room a thorough cleaning to get it ready for the next guest. This takes 25 minutes. If a guest is staying another night, the housekeeper only “refreshes” the room, which takes 20 minutes. Each day, each housekeeper reports for her 6- hour shift, then prepares her cart. She pushes the cart to her floor and begins work. She usually has to restock the cart once per day; then she pushes it back to the storeroom at the end of the day and delivers dirty laundry, etc. Here is a timetable: 1) Arrive at work and stock cart (0.10 hrs). 2) Push cart to floor (0.10 hrs). 3) Take morning break (0.33 hrs). 4) Stop for lunch (0.50 hrs). 5) Restock cart (0.30 hrs). 6) Take afternoon break (0.33 hrs). 7) Push cart back to laundry and store items (0.33 hrs). Last night, the hotel was full (all 420 rooms were occupied). People are checking out of 200 rooms. Their rooms will need to be thoroughly cleaned.
