A wheel completes 2.4 revolutions in 3 seconds.

What is the angular velocity of the wheel in radians per minute?

Enter your answer, in exact form as a simplified fraction,

 

 

Would it be 301. 6 radians per minute

3 sec  = 1/20  of a  minute

 

So....

 

2.4  * 20  =  48  revs  /   min

 

And

 

48 * 2pi   =     96 pi  rads /  min  ≈  301.6  rads / min

 

Good job, Jenny   !!!!
