Stacey is standing in a field. She walks 11 meters west, 38 meters north, 7 meters west and finally 22 meters south. How many meters is she from her starting point?
She is now 7+11 =18 m west
and 38 - 22 = 16 meters north
Pythag theorem
(distance from start)2 = 182 + 162
d2 = 324 +256
d = sqrt ( 580) = 24.08 m
