Hey there!
The answer to your question is [tex]21 mps[/tex]
To find the rate of speed, we have to find the meters per second, or mps. The formula for this is [tex]\frac{distance}{time} = speed[/tex]. So:
[tex]\frac{63}{3} = s[/tex]
[tex]21 = s[/tex]
This means that the speed is 21 meters per second, or 21 mps.
Hope it helps and have an amazing day!
