Answer 1

D. 4.75 m/s west

Step-by-step explanation:

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

• The formula for velocity is: Velocity (V) =
  `(distance (d))/(time (t))`

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:

• V =
  `(d)/(t)`

• V =
  `(95 meters)/(20 seconds)`

• V = 4.75 meters per second

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.
