I am trying to set up a spreadsheet for part numbers and how often the parts
are used according to start time and end time of the production line. I also
want the 2 breaks of 10 minutes and 1 lunch of 30 minutes included in the
formula.

Can someone please suggest a simple and effective minute formula?
