How do I convert from radians per second to revolutions per minute?

**Dexter212**)How do I convert from radians per second to revolutions per minute?

First convert radians per second to revolutions per second

Then convert revolutions per second to revolutions per minute:

Or in 1 step:

i.e. putting them both together the conversion is:

Thank you very much. Can you please help me in this question?

A car travels 10km, one wheel has a radius of 30cm, find the angle it spins when it travels the 10km.

We need to be careful and keep all of the units the same. So make sure you convert 30cm to metres first.

2) Now find out how many circumferences (revolutions) there are in 10km. So again first convert km to metres: 1km = 1000 metres.

3) Then finally convert revolutions to degrees.

i.e. 1 revolution = 360

^{o}

So the final answer is revolutions x 360

^{o}.

1) First find the circumference of the wheel. This gives us the distance the car travels when the wheel turns one revolution.

So the final answer is revolutions x 360

Thanks , This is basically what i did. I got 5305.164 revolutions. But Isaac Physics said it was wrong. BTW it asked for it in radians too. So i would assume i would have to leave my final answer as 5305?

Careful with rounding.
