correct pumping time calculation correction

[poker]

=BA2/((AW2-AT2)-((BR2+BU2+BY2))*24)
as formatted my result is -913

ba2 is barrels pumped
aw2 is finish time
at2 is pump start time
br2+bu2+by2 is any pumping delay (typed in such as 2.4)

Any guidance for this would be appreciate

What's the actual question?

I am trying to calculate the correct pumping rate, so pump finish time minus pump start time will give me the total pump time but if for some reason there is a delay in pumping I need to subtract the delay hours which are in br2+bu2+by2 which is formatted as numbers like 2.4
the volume pumped is in ba2

hope that is clearer
