Answer:
20 m/s
Explanation:
Average Speed will equal to total distance over total time. We are given our total distance equal to 180 meters and total time as 9 seconds.
Apply the formula of speed:
[tex]\displaystyle{v=\dfrac{s}{t}}[/tex]
where v is average speed, s is total distance and t is total time. Therefore:
[tex]\displaystyle{v=\dfrac{180}{9}}\\\\\displaystyle{v=20 \ \, \sf{m/s}}[/tex]
Hence, the average speed for a soccer ball is 20 m/s.
