A Jack-in-the-box toy includes two components, the jester (part A) and the box (part B). The following flowchart demonstrates its manufacturing process.

It takes two steps, A.1 and A.2, to make part A, performed by two dedicated workstations, respectively:

• A.1 has a process time of 2 minutes;
• A.2 has a process time of 9 minutes.

It takes three steps, B.1, B.2, and B.3, to make part B, performed by three dedicated operators, respectively:

• B.1 has a process time of 6 minutes;
• B.2 has a process time of 10 minutes;
• B.3 has a process time of 3 minutes.

After both parts are produced, they will be combined together to form the final product through the final assembly operations. This step takes 11 minutes and is performed by either of the two parallel workstations, C.1 and C.2. Note that C.1 and C.2 perform identical operations and each unit of product requires just one of them for 12 minutes.

What is the capacity of this manufacturing process (in units/hour)? Keep 1 decimal place if your answer is not a whole number.
