It's just d = r*t, the speed x the time (in whatever units)
--------------------------
- how does the runner's direct distance in feet from the starting line vary?
That's more complex. The lenght of the straight sections and the radius of the end sections have to be spec'd to get numerical values.
A general solution would take some work.

Same as the 2nd question.
