At the stadium, there are three lines for arriving customers, each staffed by a single worker. The arrival rate for customers is 140 per minute and each customer takes (on average) 1.1 seconds for a worker to process. The coefficient of variation for arrival time is 1.4 and the coefficient of variation for service time is 1. (Round your answerto three decimal places.) How much time (in seconds will an average customer spend in queue? seconds
