Calculate Elapsed Time in DAX

[k602570]

I'm looking for the DAX equivalent to calculate Elapsed time, incorporating both networkdays & Hours of operation. I understand the "networkdays" works around by utilizing calculate and DatesBetween on the Weekend, Holiday dates, but am struggling with a good way to account for the hours of operation.

ElapsedDays = (NETWORKDAYS(A19,B19,Holidays)-1)*($D$2-$C$2)+MOD(B19,1)-MOD(A19,1)
ElapsedHours = ((NETWORKDAYS(A2,B2,Holidays)-1)*($D$2-$C$2)+MOD(B2,1)-MOD(A2,1))*24
