Answer 2

Answer:

When both swimmers do work at the same rate.    

Explanation:

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 :

$P=\dfrac{W}{t}$

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).
