RPM

An electric motor makes 3,000 revolutions per minutes. How many degrees does it rotate in one second?

Correct answer:

c =  18000 °/s

Step-by-step explanation:

$$\begin{gathered} a=3000\text{ RPM } \\ b=a\mathrm{/}60=3000\mathrm{/}60=50\text{ RPS } \\ c=b\cdot 360=50\cdot 360=18000^{\circ }\text{/s} \end{gathered}$$
