the number on the left is the displacement, on the right is the vector. The person travelling i order of the numbers ....not sure how to explain this because there are no instructions only a shart with the titles of the categories Steps, Displacement, Vector.

I'm supposed to find the Displacement. How do I do that?

20m North

52m South

19m East

30m North

1m West

1m North

10m South

56m North

19m West

26m South

There is no magic but to resolve each and every vector into its components (East =x, North =y), and add up each component.

A well formatted table will help you organize your work. A suitable format could be:

Distance Direction(°) x-component y-component

20 90 20cos(90) 20 sin(90)

52 -90 20cos(-90) 20sin(-90)

....

26 -90 26cos(-90) 26sin(-90)

------------------------------------

Total --- x-total y-total
