These two details can be found in the graph presented, in this, the maximum distance (vertical axis) is 15 meters and at this distance, the time is 10 seconds. Now, with this information we can use the formula Average speed = Total distance ÷ Total time.
According to this, the correct answer is 1.5 m/s. Also, meters per second or m/s is the correct unit because the distance is provided in meters (m) and the time is provided in seconds (s).
