Calculating Weekly Leave Hours

[EwelinaST]

Hi, I am new to Power BI and I am struggling to calculate the leave hours per week.

I need to summarize the 'Leave Request' table so it shows hours weekly (by Week Ending Date).

The above example shows the staff member who requested holidays between 23/12-17/01 (the table already excludes weekends and bank holidays). 
I need to achieve something similar like below but with the right numbers. I know that in this instance I would need to divide weekly hours by 14, however I cannot achieve that using DAX.  I would appreciate any help with that. Many thanks.
