Consider a manufacturing process depicted by the following flowchart.

flowchart

Station A has $3$ parallel operators, A$1,$ A$2,$ and A$3.$ Station C has $2$ parallel operators, C$1$ and C$2.$ 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$,$ a unit then needs to be processed by either C$1$ or C$2.$ The process time of the individual operators are given as follows.

A$1,$ A$2,$ and A$3$: $9$ minutes

B: $14$ minutes

C$1$ and C$2$: $6$ minutes.

The process initiates the production of a new unit every $25$ minutes. What is the utilization of Station B in percentage?

Note: Provide a number without the $\%$ mark. Round your final answer to $2$ decimal places if it is not a whole number. For example, if your answer is $71\mathrm{.}723\%,$ enter $71\mathrm{.}72.$
