A - A girl delivering newspapers covers her route by traveling 4 blocks west, 2 blocks north, then 6 blocks east. What is her resultant displacement? Answer in units of blocks.
B - What is her direction? Use counterclockwise as the positive angular direction from due east, between the limits of −180◦ and 180◦. Answer in units of ◦.
C - What is her total distance? Answer in units of blocks.
went total of 6-4 = 2 blocks east (x axis)

net is sqrt (2^2+2^2) = 2 sqrt 2 northeast which is 45 degrees north of east
