Compared to yesterday, you did three times the work in one-third the time. To do so, your power output must have been ___

9 times yesterday's power output

Explanation:

Power is the rate at which a certain work is done. The unit of power is Watt and it's equal to work divided by the time taken to complete the work.

In this scenario, since the person did three times the work in one-third the time, then the power output will be:

= Work done / Time

= 3/⅓

= 3 × 3

= 9

Therefore, the power output must have been 9 times yesterday's power output.
