Answer

Brief Explanations:

Instantaneous velocity has both magnitude and direction at a specific instant. Here, the velocities in north and west directions are given at specific moments, so they are instantaneous velocities. The velocity in the northwest direction represents the overall average velocity from start - to - finish considering the displacement and total time taken for the whole motion.

Answer:

5.7 km/h north and 5.8 km/h west are instantaneous velocities, while 8.1 km/h northwest is the average velocity.
