Question from kim, a student:

Joan wants to jog 10 miles on a circular track 1/4 miles in diameter. How many times must she circle the track?

Hi Kim,

The circumference of a circle (distance around the circle) is π d where d is the diameter. What is the circumference of Joan's circular track? How many times will she have to travel this distance to have travelled 10 miles?
