To find the average time spent on surveys in Power BI when the hours and minutes are in different columns, you can follow these steps:

Assuming you have two columns named "Hours" and "Minutes" to represent the time spent on surveys, you can combine them into a single column and then calculate the average. Here's how you can do it:

1. Combine Hours and Minutes into a Single Column: You can create a custom column that combines the hours and minutes into a single time duration column. You can use the Power Query Editor to do this. Follow these steps:

   • Open Power BI Desktop.
   • Go to "Home" > "Edit Queries" to open the Power Query Editor.
   • Select the table containing your survey data.
   • Go to the "Add Column" tab and select "Custom Column."

   In the "Custom Column" dialog, use a formula like this to combine hours and minutes:

Duration.From([Hours] & ":" & [Minutes])

1. This will create a new column that combines the hours and minutes into a time duration.

2. Calculate the Average Time: After you've combined the hours and minutes into a single column, you can now calculate the average time spent. Here's how:

   • Close the Power Query Editor, and you'll see the new combined column in your data table.
   • Create a new measure to calculate the average duration. Go to the "Modeling" tab and select "New Measure."
   • In the formula bar for the new measure, use the AVERAGE function to calculate the average duration:

Average Duration = AVERAGE('YourTableName'[CombinedTimeColumn])

1. Replace 'YourTableName' with the name of your data table and 'CombinedTimeColumn' with the name of the column where you combined hours and minutes.

Now you have a measure called "Average Duration" that gives you the average time spent on surveys. You can add this measure to your visuals and reports to display the average time.

Make sure that the "CombinedTimeColumn" in your model is set as a duration data type so that the AVERAGE function can calculate the average correctly.

Is there any chance that you can create a column and do all your calculations in minutes? 
When you get the result that you want (in minutes), you can then adapt one of these to format as hh:mm:
