Excel/Excel throughput Question


Version 2010
Calculating time to process inserting time X inserters to generate minutes to process.

A   Insert rate pp/hr      730
B   Number of inserters      12
C   Pieces      2475
  C/(A*B)*60      16.95205479
  C/(A*B)*60/1440      16:57
The time calculation reflects a difference of 35 seconds to the straight thru calculation.  How do I get them to match for processing minutes?


(first answer had the wrong units.  Here is a revised answer)

16.95205479   is 16 full minutes plus  .95205479 of a full minute which is equal to 57.1232874 seconds.  So if I round to full seconds, then it is  16 minutes and 57 seconds

in your second calculation, you get the same thing:  16 minutes and 57 seconds.

I am not sure where you see a difference of 35 seconds.  To me, the results look equal.
