The top blade of the electric fan is 1.5 feet away from the rotating shaft. If the electric fan rotates at the maximum speed of 1760 per minute, how many miles can the top blade of the electric fan walk in an hour?

This is very simple. According to the question, the radius of this circle is 1.5 feet, so the distance of a circle is 2π r.

This is a simple calculation: 60×1760× 2π×1.5/5280 = _ _ _ _ _
