As the particles are moving at the same rate, their speed is the same but velocities will be different beacuse their directions will be different.

Two escalators move people up and down between floors of a shopping ma...
Explanation:
When people use escalators, they move with the escalator in the same direction, either up or down. Therefore, the motion of the people and escalators are the same. The question asks about the motion of the escalators, not people.
Velocity and speed are different concepts in physics. Velocity is a vector quantity that includes both speed and direction, while speed is a scalar quantity that only represents magnitude.
- Velocity of the escalators: Since the escalators move in opposite directions, their velocities are in opposite directions as well. Therefore, their velocities are not the same.
- Speed of the escalators: The question states that the escalators move people up and down between floors of a shopping mall at the same rate. Therefore, their speeds are the same.
Therefore, the correct answer is option 'D': The escalators have the same speed, but different velocities.
