A child on a barber shop spins on a stool. If the child turns counterclockwise through 8.0 radians at a certain time and with an angular velocity of 2.56 rad/s. What is the time interval in minutes when the child turns?

Answer 1

8.0 rad / (2.56 rad/s) = 8.0/2.56 = 3.125 s

Now convert that to minutes...
