Assume the arrival rate is$5$boats per hour and that the service rate for each server is$10$boats per hour c$.$what is the average time a boat will spend waiting for service? d$.$what is the average time a boat will spend at the dock? E$.$If customers expect to able to be in and out of the marina within$10$minutes on average, does this system provide acceptable service? f$.$ The manager of Fore and Aft is interested in balancing good customer service with teh cost of providing this service. To achieve this, the manager would like the customer's average time in the system to be as close to $10$ minutes as possible, but not exceeding $10$ minutes.
