Question 4
part a ) find the average speed which is = total distance / total time
find the total distance : distance to the south + distance to the west
find the total time : time taken to the south + time taken to the west
part b ) Find the magnitude & direction of average velocity
magnitude = total displacement / total time
direction = same as the direction of the displacement ( I Think )
find the total displacement which is the difference distance between the west and south.
total time is the same that found out in part a .
