Calculate Average Time Elapsed in Days, hours and minutes

[Nina46]

Hi!



Im trying to calculate the average time elasped in 2 columns in Days, Hours and Minutes format. I have used

=INT(I10-H10)&" Days, "&HOUR(I10-H10)&" Hours, "&MINUTE(I10-H10)&" Minutes"

to get the time elapsed. However, when I try to get the average in the column I get either #DIV/0 or #Value! error message.

Some of the time elapsed goes over 30 days so just using I10-H10 doesnt give the correct answer in those instances.

Help!

Copy of some of the document below.
