Given,

Work done = 350 Joules

Power = 125 Watt

To find,

Time taken

Solution,

The time taken by the runner to do the work of 350 Joules and to make 125 Watt power is 2.8 sec.

We can simply find the time taken by the runner by using the formula

Power = work done / time

Time = Work done / power

        = 350/125

        = 14/5

        = 2.8 sec

Hence, the time taken by the runner to do the work of 350 Joules and to make 125 Watt power is 2.8 sec.
