a fly moves from one corner of the floor of a room and you are standing opposite corner into the room .Describe the displacement of the fly when it covers half of the distance.

If the fly is walking on the floor toward the opposite corner, the distance to the corner can be represented by a sloped line. Using the
coordinates of the end points, the mid
point formular can be used to calculate the coordinates of the mid
point and distance:
(X1,Y1),(Xo,Yo),(X2,Y2).
Xo = (X1+X2)/2.
Yo = (Y1+Y2)/2.
Do = sqrt((XoX1)^2 + (YoY1)^2)) = Middistance.
