A police officer is checking the license and registration of the
vehicles crossing a control
point. The officer takes 2 minutes per vehicle to check the
information. After 45 minutes,
a second officer arrives (also needs 2 minutes per vehicle). If
vehicles arrive at a rate of 40
vehicles per hour, answer the following:
a. What is the average queue length?
b. What is the maximum queue length?
c. What is the average waiting time in queue?
