which statement correctly compares speed to velocity?

A. Speed is how fast an object is moving over distance/time. Velocity is only the direction that the object travels.

B. Speed is how fast an object is moving over distance/time. Velocity is the rate at which an object changes position, , over displacement/time

C. Velocity and speed mean the same thing

D. Velocity is how fast an object is moving over distance/time. speed is the rate at which an object changes position, over displacement/time

Answer:

B. Speed is how fast an object is moving: speed = distance/time.

Velocity is the rate at which an object changes position: velocity = displacement/time

Explanation:

Distance is a scalar quantity. It has only magnitude. 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 vector quantity. It has both magnitude and direction 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

A It can't be because becasue velocity is notthe direction of an object

C It cant be c its does not mean the same thing

D It cant be d because they have the definitions mixed up

So your best bet is to go with B Speed is how fast an object is moving over distance/time. Velocity is the rate at which an object changes positon, over displacement/time

Hope this helps
