Answer: 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)
