Explanation & Answer

Thank you for the opportunity to help you with your question!

the circumference of the circle is pi*diameter

C=3.14*23=72.257 in.

now for one revolution it the wheel takes 1/47 minutes.

hence the velocity of a point in on the wheel is distance/time

=72.257 in./(1/47 min.)

=(72.257*47) in./m

=3396.062 in/min

=3396 in/m to the nearest in/m

Please let me know if you need any clarification. I'm always happy to answer your questions.
