Quizplus · Accepted Answer

The average demand is 43 windows per day, and Alex can produce 96 windows per day (8 hours * 60 minutes / 5 minutes per window). Using the formula for average waiting time in a single-server queue (Little's Law), the average waiting time is (43/96) * (5 minutes) = 2.03 minutes.
