How about something like:

=SUMIF(A1:A9,">""",B1:B9) / COUNTIF(A1:A9,">""")

Not sure I interpreted your needs correctly. Is the result you're expecting
16.667 or is it 40?

If you're looking for a result of 40, you're going to be better off putting
an indicator in column A like "Total" or other phrase that a formula can key
off of to do the counting of entries and identifying what to add and divide
by.
