D. 4.75 m/s west

Explanation:

You can immediately get the answer once you know the formula for velocity.

The distance is 95 meters while the time is 20 seconds. All you have to do is to divide 95 meters by 20 seconds.

Let's solve:

Since Brenda is going west with her her skateboard, then you have to add west as her direction.

Brenda's velocity is 4.75 m/s west.

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions
