- The formula for velocity is: Velocity (V) =

The distance is 95 meters while the time is 20 seconds. All you have to do is to divide <u>95 meters by 20 seconds</u>.
Let's solve:
- V =

- V =

- V = 4.75 meters per second
Since Brenda is going west with her her skateboard, then you have to add <em>west </em>as her direction.
