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]
