elapsed time average calculcations

[relux]

Hey guys,

Here is my situation. I have a formula in Column F that is:

=INT(D3-C3)&" days, "&INT(24*MOD(D3-C3,1))&" hours, an
"&ROUND(60*MOD(24*(D3-C3),1),0)&" minutes"

It takes the time from column c and d and shows the elapsed time. Wha
I need to do now is make a field in for example F 30 that shows th
average elapsed time. In other words, average up all the elapsed time
in Column F. I can't figure out a way to do this..

Also, I have the formula above all the way down the spreadsheet. I
there a way to hide "0 days, 0 hours, and 0 minutes" if there i
nothing in the C and D columns?


I've attached the spreadsheet..


Thanks in advance

I'm afraid you would need VBA to do this.
You can have a look at the function Datediff(), maybe you can figur
out a way with cell formulas to get it done but I don't

spreadsheet..

First part,

I would use

=SUMPRODUCT(--((D320<>"")*OR(C3:C20<>"")),(D320-C3:C20))/SUMPRODUCT(--((
D320<>"")*OR(C3:C20<>"")))

Second part

=IF(AND(D3="",C3=""),"",INT(D3-C3)&" days, "&INT(24*MOD(D3-C3,1))&" hours,
and "&ROUND(60*MOD(24*(D3-C3),1),0)&" minutes")

Thanks for the response. However, what you say is for the second part I
am assuming would replace my current average formula. I dont think I
quite understand what the first forumala is for...

My fault, looks like it gives the average time in days. Can this be
modified to give the average in minutes?

Thanks soo much!

No, it gives the average time in time. Format the cell as time.
