Gabriella and Michelle are a few meters apart, at one end of a football field. Pierre is at the other end of the field, and he sees both of them mov- ing toward him at 4 m/s. From Michelle's point of view, how is Gabriella moving?

She is not moving.

Explanation:

It is stated that Pierre is observing both of them the same way which means that they are both moving in the same direction at the same speed, 4m/s. According to the relative speed concept, they will observe each other according to the difference in their movement directions and speed. Since they are moving in the same direction and at the same speed, Gabriella will be observed as if not moving from Michellle's point of view.

I hope this answer helps.
