1. An airline terminal has several terminal gates at the Hartsfield International Airport in Atlanta. Under normal conditions the airline assigns one operator to the desk at each gate to serve passengers, including making seat assignments, checking passengers in, rerouting passengers, and solving customer problems. At one specific gate that is in constant use throughout the day, passengers arrive at the desk at the rate of 80 per hour according to a Poisson distribution. The airline agent is able to serve passengers in an average time of 0.667 minutes, exponentially distributed. Determine L, Lq, W, and Wqfor this waiting line system, and indicate if it seems adequate to be perceived as quality service.
