A person walks first at a constant speed of 4.90 m/s along a straight line from point circled A to point circled B and then back along the line from circled B to circled A at a constant speed of 2.90 m/s. Find the average Velocity for the time interval of 1.80s to 2.80s and also the average velocity for the time interval of 1.85s to 2.25s.
