See the three processes above to answer this question. Each of the three processes include $3$ steps in the process. For all but one workstation, there is one worker $($indicated by an icon of a person$).$ For the second process, at workstation A$,$ there are two workers. They are equally capable and it takes a single worker $6$ minutes to complete step A in the process. With the two workers, the first worker works on the first unit that shows up their station, then the second worker works on the second unit, so they are working simultaneously.
