A.Speed requires distance. Velocity requires direction.

Explanation:

The difference between speed and velocity is:

- Speed is a scalar, so it consists only of a magnitude, which is defined as the ratio between the distance covered and the time taken:

\(s=\frac{d}{t}\)

So, speed requires distance

- Velocity is a vector, so it requires both a magnitude (which is equal to the speed) and a direction. Therefore, velocity requires a direction.
