Question

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

Answer 1

One revolution is 360 degrees. And one minute has 60 seconds.

So, let's find out how many revolutions it makes per second, and then from there, find out how many degrees.

Answer 2

If it rotates 3,000 revolutions per minute then it will rotate\[\frac{3000}{60s}=50s^{-1}\]Since each revolution is 360 degrees and it does 50 complete revolutions per second, what do you think the answer is?
