Answer:
B) equal, different
Explanation:
- Speed is the ratio between the distance covered by an object and the time taken:
\(v=\frac{d}{t}\)
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:
\(v=\frac{s}{t}\)
and a direction.
In this problem, the two cars have same speed (25 m/s) but different velocities, because they travel in different directions.
