An electric motor turns at 2400 revolutions per minute or 2400 r/m.
Find the angular velocity, in radians per second, in exact form and in approximate form, to the nearest hundredth.
--------
This is what I've done so far and I don't know what to do next ...
2400 r/m divided by 60s = 40
---------
Answer: 80pi rad/s, 251.33 rad/s
