Consider a CPU that has to execute two types of processes. The first type, Actuators (A), requires a CPU burst of 6 seconds. The second type, Controllers (C), requires a CPU burst of 8 seconds. A new process of type A arrives at time \(t = 10, 20, 30, 40,\) and \(50\) (in seconds). Similarly, a new process of type C arrives at time \(t = 11, 22, 33, 44,\) and \(55\) (in seconds). The CPU scheduling policy is First Come First Serve (FCFS). The first process of type A starts running at \(t = 10\) seconds. The average waiting time (in seconds) for the 10 processes is ___________.
