Answer:

B) equal, different

Explanation:

- Speed is the ratio between the distance covered by an object and the time taken:

[tex]v=\frac{d}{t}[/tex]

And it is a scalar, because it has only a magnitude, so it does not depend on the direction of the motion.

- Velocity is instead a vector, consisting of a magnitude (which is equal to the ratio between the displacement and the time taken:

[tex]v=\frac{s}{t}[/tex]

and a direction.


In this problem, the two cars have same speed (25 m/s) but different velocities, because they travel in different directions.
