Calvin's mom chases Calvin around the house, running at constant speed in a perfect circle of radius 20 m. She completes 5.5 revolutions in 5 minutes before catching Calvin. What was Mom's speed during this time?

What was the magnitude of Mom's average velocity during this time? Hint: Make a drawing!

What was the magnitude of Mom's acceleration during this time?

Thank you
