Four electric motors each do an equal amount of work when they raise a weight of $10\,\text{N}$ over the same distance. The time intervals taken by each motor to raise the weight are shown. What is the time taken by the motor that produces the greatest power?
- A$1.5\,\text{s}$
- B$6.0\,\text{s}$
- C$15\,\text{s}$
- D$60\,\text{s}$
