Consider a process that has 3 stations, ordered in sequence: 1, 2, and 3. At each station, two consecutive tasks are performed one after the other. The time (in seconds per unit) it takes for a single person to perform each task is given in the table below (e.g., task A2 takes 10 seconds per unit):

Station	# of Workers	Task A1	Task A2	Task B1	Task B2	Task C1	Task C2
1	1	20	10	-	-	-	-
2	2	-	-	40	40	-	-
3	1	-	-	-	-	1

The table also gives the number of workers at each station. What is the capacity of this process (in units per minute)? (Round the answer to 1 decimal place.)

Capacity of this process units/minute.
