Answer:
B. <em>Speed</em> is how fast an object is moving: speed = distance/time.
<em>Velocity</em> is the rate at which an object changes position: velocity = displacement/time
Explanation:
<em>Distance</em> is a <em>scalar </em>quantity. It has only <em>magnitude</em>. So, distance/time is also scalar. If you are travelling at 100 km/h, that is your speed, because you could be going in any direction.
Displacement is a <em>vector </em>quantity. It has both <em>magnitude and direction</em> So, displacement/time is also a vector. If you are travelling east at 100 km/h, that is your velocity, because you are stating both your speed and the direction
