Averages in measures

[KGBOR]

Hello, 

I'm facing the following issue. I need to calculate the average durations for specific days/timeframes however when I want to format my measures I don't have neither the time nor the duration as an availalbe format for it. What can I do in this case? 

Thank you!

I'm not sure what you are looking for. Is the provided example your data or your desired output?
What did you try and what incorrect result did it return? What do you mean by format for duration? Are you looking for second? hours? centiminutes/hours? Are you looking for "mm:ss" format?

The picture is the example of my data.  When I create a measure based on that I have no option to select time or duration as a format (see attached picture), so yes I'm looking for a "mm:ss" format for my measure however.
