Instead of having another student help Lenny, the manager is thinking of having two lines instead. Customers will equally divide themselves between the two lines
How long will students wait in line if there's a second server? (Assume that the service time is 5 minutes.)
Lenny, a graduate research assistant "moonlights" at the short order counter in the student union snack bar in the evenings. He is the only one on duty at the counter during the hours he works. Arrivals to the counter seem to follow the Poisson distribution with a mean of 8 per hour. Each customer is served one at a time and the service time follows an exponential distribution with a mean of 5 minutes.
Answer: The arrival rate will be cut in half but the service rate remains the same. Waiting time in line is .04 hours or 2.5 minutes or 150 seconds.
