Help required to display whole number/decimal to mm:ss in Power BI Visual Matrix

[DeeMag]

Hi, 

Please can someone help me on converting the whole number to display as mm:ss for the values which are on the matrix visual.

The Brand and Average Duration are in the matrix visual.

The Average Duration for 163 should be displayed as 02:43 or something like in mm:ss

Any help on this appreciated, thank in advance. if any more inputs are required to work on this, please let me know.

Regards,

As per other post, in power Query, I changed the column type to duration and  Data type to Date/time.

Added a measure as 

Avg Time =

FORMAT( AVERAGE('Table'[Duration]) , "mm:ss"), but the values are not correct.
