Question

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.

Answer 1

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
co-ordinates of the end points, the mid
-point formular can be used to calculate the co-ordinates of the mid
point and distance:

(X1,Y1),(Xo,Yo),(X2,Y2).

Xo = (X1+X2)/2.

Yo = (Y1+Y2)/2.

Do = sqrt((Xo-X1)^2 + (Yo-Y1)^2)) = Mid-distance.
