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 10, 20, 30, 40, and 50 (in seconds). Similarly, a new process of type C arrives at time 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 seconds. The average waiting time (in seconds) for the 10 processes is ___________. (*rounded off to one decimal place*)
