Answer:
The speed of the ball is 28.4m/s.
Explanation:
Given that the formula of speed is Speed = Distance/Time. So you have to substitute the values into the formula :
[tex]speed = distance \div time[/tex]
Let distance = 91m,
Let time = 3.2s,
[tex]speed = 91 \div 3.2[/tex]
[tex]speed = 28.4 \: metrepersecond[/tex]
