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
So average Speed = 100 cm / 2 seconds = 50 cm / second
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/s
So the average speed of the ball is 50 centimeters per second.
