Question

which explains the information needed to calculate speed and velocity?
both require the total distance, but velocity also requires time and displacement.
both require time, but velocity requires displacement and speed requires distance.
speed requires displacement, while velocity requires distance.
speed does not require time, while velocity does require time.

Explanation:

Speed is a scalar quantity calculated as $\frac{\text{total distance}}{\text{time}}$, so it needs distance and time. Velocity is a vector quantity calculated as $\frac{\text{displacement}}{\text{time}}$, so it needs displacement and time. Both rely on time, with the key difference being the use of distance (for speed) vs. displacement (for velocity).

Answer:

B. Both require time, but velocity requires displacement and speed requires distance.
