Accepted Answer
Answer: 50 centimeters per second.Explanation: The ball travels a distance of 100cm in a span of 2 seconds, then, the speed of the ball can be calculated as:S = (distance moved)/(total time) = 100cm/2s = 50cm/sSo the average speed of the ball is 50 centimeters per second.
Suggested Answer
average speed is defined as distance traveled divided by time duration to cover the distance.So average Speed = 100 cm / 2 seconds = 50 cm / second
