Answer
Therefore, the direction of the average velocity is $63.4^{\circ}$ south of east.
Work Step by Step
In part (b), we found that the direction of the displacement is $63.4^{\circ}$ south of east.
Note that the direction of the average velocity is in the same direction as the displacement.
Therefore, the direction of the average velocity is $63.4^{\circ}$ south of east.
