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 distance divided by time ($s = \frac{d}{t}$), where $d$ is distance and $t$ is time. Velocity is a vector quantity calculated as displacement divided by time ($v=\frac{\Delta x}{t}$), where $\Delta x$ is displacement and $t$ is time. So both require time, speed requires distance and velocity requires displacement.

Answer:

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