Power is defined as rate of work done or rate of energy
so here we can say that
![Power = (Work)/(time)](https://img.qammunity.org/2020/formulas/physics/high-school/5bspumty4swqo0nwnb0sclrxgibr1zz9wd.png)
so here correct answer must be
how much work can be done in a given time.
So we need to find the work done in a given period of time and then we will have to find the ratio of total work done and total time taken.
