Commercial trucks begin to arrive at a seaport entry plaza at 7:45 am, at the rate of Lambda(t) = 5 - 0.03t (where Lambda(t) is in veh/min and t is in minutes). The plaza opens at 8:00 am. For the first 15 minutes, one processing booth is open. After the first 15 minutes until the queue clears, two processing booths are open. Each booth processes trucks at a uniform rate of two trucks per minute. What is the average delay per vehicles, the total delay, and the average queue length?

Selected Answer: Total delay: 8241.99 min Avg delay/vehicle: 21.65 min/veh Avg queue length: 70.05 veh Response Feedback: CORRECT!!!! Great job :D
