Finding an average physical CPU circuit length

If you know the clock speed and this is set based on the worst-case signal propagation in a CPU, can you figure out how "physically" long an average circuit traverse is for a particular benchmark algorithm? What would be an average physical circuit length range (i.e., path length) in a typical modern CPU? Could this be related to the die length (fraction or integer multiples)? Is there any reliable way to calculate a gross signal propagation speed in terms of a fraction of light speed? Is there any good reference concerning CPU propagation speeds and physical circuit lengths within the CPU?

Many thanks in advance for any answers!

There's an assignment question for a course if I ever saw one.

^+1. Anyways, intresting question. I would answer if I knew the answer. My background on electrical theory,etc is lacking.
