If you have swam one lap in a swimming pool, that means you have swam from one end to the other and back. In 2 h, a swimmer makes exactly 58 laps in a swimming pool that is 47 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.

Question

a.) Distance in km

b.) Displacement in km

c.) Average velocity in km/h

d.) Average speed in km/h

If instead, the swimmer makes 58.5 laps in the same pool in 2 h, determine the total distance the swimmer traveled, the swimmer's total displacement, the swimmer's average velocity, and the swimmer's average speed.

e.) Distance in km

f.) Displacement in km

g.) Average velocity in km/h

h.) Average speed in km/h

Answer 1

a. d = 58Laps * (2*47)m/Lap = Distance in m. Divide by 1000 to change to
km.
b. D = straight line distance from starting point to the end = 0 km.
c. V = D/t = 0/2 = 0.
d. Speed = d/t

Answer 2

e. 58.5Laps * (2*47)m/Lap = distance in m. Change to km.
f. D = 0.5Laps * (2*47)m/Lap = Disp. in m. Change to km.
g. V = D/t.
h. Speed = d/t.
