A displacement is a length with a particular direction, and therefore can be represented by a vector. An explorer travels a displacement of 20 km at an angle of 30 degrees from east, then 30 km at 45 degrees from east, then 20 km 120 degrees from east, and finally, 10 km at 240 degrees from east. Label each of these displacement vectors A, B, C, and D, respectively. All angles are measured counterclockwise from the east axis.
(a) Determine the total distance traveled by the explorer in meters.
(b) Choose a scale, and using a protractor and a ruler, add the displacement vectors on the graph.

Does it help?

I kinda figured that one, I just need the graph of all of it...
