Final answer:
Electricians can complete approximately 3 rooms per day if they work 8 hours daily and it takes 2.6 hours to outfit a room with outlets. Over the course of 5 days, they would complete around 15 rooms.
Step-by-step explanation:
The student is inquiring about calculating the number of rooms completed by electricians installing outlets over a course of five days. To solve this, we first determine the daily productive hours. Given that the electricians work 8 hours a day, and it takes 2.6 hours to install outlets in one room, we can calculate the number of rooms they can complete in a single day by dividing 8 hours by 2.6 hours, which results in ≈3.08 rooms per day. However, since we cannot have a fraction of a room, we round down to 3 rooms per day.
Next, we multiply the number of rooms completed in a day by the total number of days worked, which is 5 days. So, 3 rooms/day × 5 days equals 15 rooms. Therefore, over five days, the electricians can complete 15 rooms.
