displacement is the measure of the distance from the starting and ending points, AND the direction.
it doesnt matter that she ran 300m total.
heres the math for displacement:
point b (the direction with the larger number) - point a(direction with the smaller number
the direction will be point b's direction.
so, plug it in.
200m west - 100m east
if u wer to draw displacement, you would not need 2 draw the 200m west or the 100m east; you would imply draw the starting point and then 100m west, and draw a straight line connecting them.
^^ hope this helps!
