Question

It takes a person 22 seconds to swim in a straight line from the south end of

a pool to the north end of the pool, a distance of 28 meters. What is the
swimmer's velocity?​

Answer 1

1.3 m/s north

Step-by-step explanation:

Answer 2

1.27 m/s.

Step-by-step explanation:

The following data were obtained from the question:

Displacement (D) = 28 m

Time (t) = 22 secs

Velocity (v) =?

Velocity is simply defined as the rate of change of displacement of an object with time. It can be represented mathematically as:

Velocity (v) = Displacement (D) /Time (t)

v = D/t

With the above formula, we can obtain the swimmer's velocity as follow:

Displacement (D) = 28 m

Time (t) = 22 secs

Velocity (v) =?

v = D/t

v = 28/22

v = 1.27 m/s

Therefore, the swimmer's velocity is 1.27 m/s.
