Question

Brenda rode a skateboard 95 meters west. It took her 20 seconds. What was

Answer 1

Answer:

D. 4.75 m/s west

Explanation:

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

• The formula for velocity is: Velocity (V) = $\frac{distance (d)}{time (t)}$

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 = $\frac{d}{t}$

• V = $\frac{95 meters}{20 seconds}$

• 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.
