Answer:
The passengers have an average of 8.15 minutes to wait in line
Step-by-step explanation:
Using Little's law
Average Inventory = Average Flow Time * Average Flow Rate
Average Inventory = 220 passengers
Average Flow Rate = 27
Average Flow time =?
So,
220 = Average Flow Time * 27
Average Flow Time = 220/27
Average Flow Time = 8.14814814814
Average Flow Time = 8.15 --------- Approximated
So the average wait time for a passenger is 8.15 minutes
