Traffic Flow and Queuing Theory.

Vehicles leave an airport parking facility (arrive at parking fee collection booths) at a rate of 500 veh/h (the parking facility has a policy that the average time a patron spends in a queue waiting to pay for parking is not to exceed 5 seconds. If the time required to pay for parking is exponentially distributed with a mean of 15 seconds, find the average time in system.
