At a border inspection station, vehicles arrive at the rate of 10 per hour in a Poisson distribution. For simplicity in this problem, assume there is only one lane and one inspector, who can inspect vehicles at the rate of 12 per hour in an exponentially distributed fashion. a. What is the average length of the waiting line? (Round your answer to 2 decimal places.) Average length Answer is complete and correct. 4.17 customers b. What is the average time that a vehicle must wait to get through the system? Average time Answer is complete and correct. 30 minutes
