At the Hartsfield International Airport there is one booth leading into the MARTA rapid transit station. The booth has three windows for selling tokens and providing information for arriving transit passengers, who form a single line and are served by the first available agent. Customers arrive at the average rate of 180 per hour. Each window agent is able to service customers at the average rate of 70 per hour. (Both arrival rate and service rate is Poisson distributed.) Determine the average number of passengers waiting and the average waiting time. At the Hartsfield International Airport there is one booth leading into the MARTA rapid transit station.
