You're biking and you come across a hill. There's 3 routes you can take:
- A 1 mile road to the top with a 12% grade
- A 3 mile road to the top with a 4% grade
- A 9 mile road around the hill to the other side with a 0% grade
Which do you take, and why?
Edit: that's 633 feet of climbing for choices 1 and 2, by the way.
