25/37 is what i believe the answer is. 25 feet down for every 37 feet over.

The plane descends 44,000 feet vertically, while travelling
13 x 5280 = 68,640 feet horizontally. So if the angle of
descent is x, then the side 44,000 is OPPOSITE to x , and
the side 68,640 is ADJACENT to x. Opposite and adjacent
are connected by the tangent ratio, so:
tan x = 44,000/68,640.
I`ll leave you to work it out. Hope it helps, Twiggy.

Slope is rise (or fall, here) over run. So it’s -44000 over (13 times 5280). Do it on a calculator and round it.
