We have a process with five steps; each step occurs in order. All product must go through each step.

Each workstation can work on one item at a time. The number of workstations for each step, as well as the flow time for each step, is given here:

# of workstations Time to complete each item $($sec$)$

$1320$

$2213$

$3528$

$4421$

$516$

Assuming we are not being starved by raw materials supply, blocked by demand, or somehow otherwise slowed down by breakdowns or the like, what is the throughput rate of the process, in items$/$sec$?$ Please use four significant figures in your answer.
