I have a chart that contains time per task and then adds the tasks for a grant time total. Example:
0:05 wash hands
0:10 brush teeth
0:20 shave
0:35 - total morning prep time

In my chart the total time is currently 63:25:00 or
2d 15h 25m

I want to break this down into a number that can be compared to a work week. In other words, if a typical work day is 8 hours, can I break this down to show work days and remaining hours and minutes? I'd like it to break down as:
?days ?hours ? minutes
where days is an 8 hour day, not a 24 hour day

Thanks.
