Calculate Average from Measure

Dear All,

please forgive me, i saw calculation for average of measure has quite some threads but i couldnt understand the solution

provided to the topics there.

So please let me share my condition.

I created Measures to collect Cycle Time for a product broken down (Assembly, Test, Prep,...)

Then i have one Measure to summarize them all for the total (Passdown_Total).

Now i need the DAX for average of the total (Passdown_Total)  for monthly average table.

Thank you
