Vehicles leave an airport parking facility (arrive at parking fee collection booths) at a rate of 366 vehicle/h (the time between arrivals is exponentially distributed). 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 7 seconds. If the time required to pay for parking is exponentially distributed with a mean of 16 seconds, what is the smallest number of payment processing booths that must be open to keep the average time spent in a queue below 7 seconds?
