0,0= Midpoint
44.7=Distance
The guy above me did some errors on the distance. 20x20=400 + 1600=40x40
2000 squared is 44.7

the midpoint is (0,0)
the distance is 20^2 + 40^2 = C^2
400 +2000 = C^2 distance is square root of 2400 (or about 48.98979486)

Consider the two points are (x1, y1) and (x2,y2) then the midpoint between them is
(x1+x2)/2, (y1+y2)/2
and the distance between them is
sqrt( (x1-x2)^2 + (y1-y2)^2)
so for your question
Midpoint is (0,0) and distance = sqrt(400+1600)=sqrt(2000)
= 20sqrt(5) or 44.72
