A gas station is a queueing system with one fuel dispenser. The site at the station allows no more than five cars to be queued for refueling at the same time. If there are already five cars in the line, the next car arriving at the station does not get into the line. The ow of cars arriving for refueling has an intensity of = 2 (cars per minute). The rate of the service is = 2.

2. On the average, how much time one car waits in the line?
