If you have swam one lap in a swimming pool, that means you have swam from one end to the other and back. In 1.5 h, a swimmer makes exactly 77 laps in a swimming pool that is 27 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 answer

Distance = 54m/lap * 77laps = 4158 m.

Displacement = Df-Do = 0-0 = 0.
Do = Starting point.
Df = Final distance from starting point.

V = D/t = 0/1.5 = 0

r = d/t = 4158/1.5 = 2772 m/h.=1.73 mi/h
