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.)
