Friends tell you that on a recent trip their average velocity was +20 m/s. Is it possible that at any time during their trip their velocity was -20 m/s? Explain, and give an example to justify your answer. PLEASE HELP

Explanation:

Velocity is a vector quantity. Velocity = speed +direction.

In this problem, we can say that any time during their trip their velocity was -20 m/s. It is due to the above reason that the velocity is a vector.

When the displacement of the object is negative, the average velocity will be negative.

For example, when an object moves in the negative direction, it will have negative velocity.
