1. Megan Airport Nogan Airport has three runways. The airport dedicates two runways to serve departing flights and one runway to serve arriving flights. If used for departure, a runway can serve 10 flights per hour; if used for arrival, a runway can serve 15 flights per hour. The coefficient of variation of the time it takes for a plane to use a runway (either to depart or to land) is 1. The flight schedule in the morning is as follows. The time between two consecutive departing flights is exactly 5 minutes . The time between two consecutive arriving requests is on average of 10 minutes with coefficient of variation of 1. When an arriving flight approaches the airport, it radios the control tower and requests permission to land. The air traffic controller responds instantly by assigning the plane a position in queue on a first-come-first-serve basis. (a) On average, how much time elapses between a plane's radioing of the control tower and its eventual completion of the entire arriving process in the morning?
