Answer

Brief Explanations:

Speed is a scalar quantity representing how fast an object is moving, with only magnitude and no direction. The first option has a direction (westward) so it's velocity. The second and fourth options are about position, not speed. The third option gives the rate of a dog's running without a specific direction, which is speed.

Answer:

A dog runs an average of 8 mph.
