Thread: revolutions per minute??

When a car's engine makes less than about 200 revolutions per minute, it stalls. What is the period of the rotation of the engine when it is about to stall?

The period is the time for 1 revolution, so if you have 200 in 1 min, you have
1 in 1/200 min, or 0.3 seconds.

So the period is 0.005 min (=0.3 s)
