--------------
Depends on his direction.
Also, he might make a turn.
You can put this solution on YOUR website! Assuming all of the mile markers are all the same distance apart, we can write a proportion for this one:
which can be solved by cross-multiplying (or by inspection)
2x = 60
x = 30 or mile marker 30
