After assembly, the computers are moved to a separate burn$-$in area that is separate from the assembly line. Here, computers are put in racks for a $24-$hour $$burn$-$in$$ of the circuit components. After burn$-$in$,$ the computer is tested again, software is installed, and the finished notebook computer is packaged and placed on pallets for shipment to distribution centers around the world.

Tweaking the Initial Assembly$-$Line Design

From past experience, the engineering manager has found that the initial assembly line design supplied by the engineers often needs to be tweaked. Consider the following questions that the engineering manager is considering:

If the assembly line is to be redesigned to operate at $315$ units per day without using overtime, what is the maximum cycle time to meet this production rate?

Note: Round DOWN "maximum cycle time" values to the next smallest integer.
