There are ten equal parts to a circular track for 2 toy cars and the distance from the inner to the outer is 3.4 inches. What is the width of the track?

Answer 1

You said that the distance from the inner track to the outer track is 3.4 inches
Isn't that the width of the track??

I think there must be more to this question.
Where does the "ten equal parts" come in?
