Answer:
To find the speed of the rolling ball, we can use the formula:
Speed = Distance/Time
where distance is measured in units such as meters, centimeters, or kilometers, and time is measured in units such as seconds or hours.
In this problem, the distance traveled by the rolling ball is 80 cm, and the time taken to travel this distance is 20 seconds.
So we can substitute these values into the formula to get:
Speed = 80 cm/20 s
Speed = 4 cm/s
Therefore, the speed of the rolling ball is 4 cm/s.
