Two swimmers compete in a race. Under what condition do the swimmers have the same power?

When one of the swimmers crosses the finish line.
When both swimmers do work at the same rate.
When both swimmers cover the same distance.
When they do different amounts of work, but take the same time.

It is given that two swimmers compete in a race. The rate of doing work is called the power of a swimmer. Mathematically, the power of any object can be written as :

[tex]P=\dfrac{W}{t}[/tex]

Where

W is the work done

t is the time taken by the swimmer

We can say that the power depends on the at rate at which the work is done. When both the swimmers do work at the same rate, then they both have same power.

Hence, the correct option is (b).
