The average time spent in the system.

Students have asked these similar questions
At an impaired driver checkpoint, the time required to conduct the impairment test varies (according to an exponential distribution) depending on the compliance of the driver, but takes 60 seconds on average. If an average of 30 vehicles per hour arrive (according to a Poisson distribution) at the checkpoint, determine the average time spent in the system in minutes/vehicle. Answer in whole number.
1. A toll booth on a turnpike is open from 8:00 a.m. to 12 midnights. Vehicles start arriving at 7:45 a.m. at a uniform deterministic rate of six per minute until 8:15 a.m. and from then on at two per minute. If vehicles are processed at a uniform deterministic rate of six per minute, determine when the queue will dissipate, the total delay, the maximum queue length (in vehicles), and the longest vehicle delay.
