If you have swam one lap in a swimming pool, that means you have swam from one end to the other and back. In 3 h, a swimmer makes exactly 30 laps in a swimming pool that is 30 m long. Determine the distance the swimmer traveled, the total displacement of the swimmer, the swimmer's average velocity, and the swimmer's average speed.

1. 1 Lap = 2 * 3o m = 60 m.

a. d = 60 m/Lap * 30 Laps. = 1800 m. = Distance traveled

b. Displacement = 0 because the starting point and end point are the same.

c.

d. S = d/t = 1800 m/3h = 600 m/h.
