Part 1: queueing review the local coffee shop has 2 employees, one takes the orders and then takes payment, and the other worker makes the coffee drinks. while some folks ask for a simple cup of coffee that just needs to be poured, others ask for more elaborate coffee drinks, and others order multiple drinks. on average, though, it takes a total of 1 min and 20 seconds to process a customer, take the order, make the payment, and make the drink(s). during the busiest time of the day, 7: 30am to 9: 30am, about 38.5 customers come in per hour.1. since the two workers only service one customer at a time, they are in fact working like a single worker. what percentage of the time is this single team of workers busy? 2. what is the average time a customer waits before they place an order? (in minutes)3. what is the average number of customers in the line?
