The Northern Tier bicycle tour route from Anacortes, Washington, to Bar Harbor, Maine, is a 4,264.5 miles long. How many more revolutions over the entire route will a 16-inch diameter wheel on a bike trailer complete when compared with a 27-inch diameter wheel on a bicycle? Please show work and explain your process step by step and the reason why you took those steps. 

Also... What's a revolution? I know I've heard of the American Revolution in my History class.. But I'm not sure in math...

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

A revolution descrides when a wheel or something circular completely goes round.

To find out how many revolutions each will make, we convert miles to inches

1 mile = 63360

4,264.5 miles = 270198720

Revolutions made by 16 inch wheel = 270198720/16 = 16887420 revolutions

Revolutions made by 27 inch wheel = 270198720/27 = 10007360 revolutions

answer = 16887420 - 10007360 = 6880060 more revolutions.

I'm always available to answer your questions.
