a speed swimmer love to race around the parks pine which is 25m around if she can swim 20 laps in 7200s what is her average speed?

the average speed of the swimmer is 0.069 m/s.

Explanation:

Given;

complete distance around the park pine, d = 25 m

total lap completed, = 20 laps

time of laps completion, t = 7200 s

The total distance completed by the swimmer = 20 x 25 = 500 m

The average speed of the swimmer = distance / time

                                                            = (500 m) / (7200 s)

                                                            = 0.069 m/s.

Therefore, the average speed of the swimmer is 0.069 m/s.
