How to calculate Average Queue Time

Hi Anonymous 
Please refer to attached sample file with the solution

Average Queue Time = 
VAR TotalTime = [Queue Time]
VAR TotalSeconds = SECOND ( TotalTime ) + MINUTE ( TotalTime ) * 60 + HOUR ( TotalTime ) * 3600 
VAR AverageSeconds = DIVIDE ( TotalSeconds, SUM ( 'Table'[Calls Queued] ), 0 )
VAR Hours = FORMAT ( QUOTIENT ( AverageSeconds, 3600 ), "00" )
VAR BalanceSeconds = MOD ( AverageSeconds, 3600 )
VAR Minutes = FORMAT ( QUOTIENT ( BalanceSeconds, 60 ), "00" )
VAR Seconds = FORMAT ( MOD ( BalanceSeconds, 60 ), "00" )
VAR Result = Hours & ":" & Minutes & ":" & Seconds
RETURN 
    Result
