Question

Two people must have the same speed and velocity if

Answer 1

If they both are moving with the same speed and direction
i.e. covering the same distance in the same time interval in the same direction

Answer 2

In general, 2 people have the same speed when their velocity vectors have the same magnitude and direction.

Step-by-step explanation:

It is possible to have the same speed for 2 bodies in 2 cases:

1.Both move in the same direction with constant velocities of equal magnitude.

2. Both bodies are under the influence of the same force under the same conditions, i.e. the force pushes the bodies in the same direction and with the same magnitude. In this way the instantaneous velocity for both bodies is the same.
