Even though coevolution often only involves two species, it can occasionally involve more. Coevolution also produces modifications that are advantageous to both parties.

Answer:

All of them

Explanation:

Since velocity is a speed and a direction, there are only two ways for you to accelerate: change your speed or change your direction—or change both. In a car you could accelerate by hitting the gas or the brakes, either of which would cause a change in speed.

2.0mph/s and 5.0mph/s
You are accelerating, meaning you wouldn’t be going negative. However if you slowed down, then you could say you’re moving at -2.0mph/s
