A bicycle with 26" wheels and axles 34" apart, traveling in a straight line runs through a spot of wet paint...  how far apart will the subsequent spots made by the front and back tires be? 

Do NOT over think this!

Why not make it a little tougher and use different sized wheels ?

We have to give folks the opportunity to over think it.

depends on the tires, which you did not specify.  The actual diameter of the tire on a 26" bike depends on the profile of the tire-- which can vary.

You are overthinking it, as long as the tires have the same profile, it does not matter.

Alright then, here is the answer regardless of the distance between the tires, if they are the same size, they will leave subsequent marks at the same distance from the original paint spot... The answer is 0.
