If A1 holds the start time (1:20) and B1 the end time (4:12) then the lapsed
time is B1-A1
If C1 hold the amount produced (2240) the =C1/(B1-A1) computes the
pounds/hour
But Excel is too helpful and display the answer in time format (11:48); we
need to format the cell as General to display which gives 18753.49. Now this
is clearly wrong since the lapse time is about 3 hours so the rate of
production is therefore approx 750 lbs/hr

The trouble is Excel stores time as a fraction of a day while it displays it
in hours. We need to convert the days to real hours using =C1/((B1-A1)*24)
which gives 781/39 lbs/hr

First of all, I posted a this same question earlier, and I received a
response, but I'm unable to open it. I also tried to search for my post in
the Excel Comm. but I can't find it. If anyone has any idea why - I'd love
to
know.

Anyway, this is what I need to do. I need to calculate the number of
pounds
produced per hour based on the following fields.

Start Time (1:20), End Time (4:12), Pounds Produced (2,240), Hours it took
to produce lbs (2.87).

I need to know how many pounds can be produced in one hour. I can't figure
this out!

Thanks,
Jason
