How do I get averages based on specific fields.

Given data such as below,
Is there and easy way to find and display in a single cell:
what is the average time (Hours:mins) for all tickets of Complete
status.
and
what is the average Hours:mins for all tickets of status=picked AND of
the type FWSnap, ?

Thanks,
Crzzy1
