Find the velocity of a swimmer who swims exactly 220 m toward the shore in 72 s.
a
3.1 m/s
b
0.33 s/m
c
3.06 s
d
0.33 m/s

3.06m/s

Explanation:

Distance covered by swimmer = 220 m

Time taken by swimmer = 72 s.

Velocity = ?

Recall that velocity is the rate of change of distance per unit time. it is measured in metres per second.

Velocity = Distance / time taken

Velocity = 220m / 72seconds

Velocity = 3.055 m/s (approximate to 3.06m/s)

catya your not at all which answer i've seen you do this on another question!
