Consider a manufacturing process depicted by the following flowchart.

Station A has $3$ parallel operators, $A1,A2,$ and $A3.$ Station $C$ has $2$ parallel operators,

$C1$ and $C2.$ Each unit only needs to be processed by one of the operators A$1,$ A$2$ and

A$3.$ After being processed at Station B $($with a single operator$),$ a unit then needs to be

processed by either $C1$ or $C2.$ The process time of the individual operators are given

as follows.

A$1,$ A$2,$ and A$3$: $24$ minutes

B: $10$ minutes

C$1$ and C$2$: $4$ minutes.

The process initiates the production of a new unit every $22$ minutes. What is the labor

productivity $($in units$/$hour$)$ of this process?

Note: $1.$ Round your final answer to $2$ decimal places if it is not a whole number.

Operators are paid even if they are idle.
