 - Is there a risk with using a greedy algorithm? You want to travel exactly 200 miles in a day. Sometimes it might be worth stopping early for a larger penalty to avoid a bigger penalty later. Does the math check out? The penalty is the distance squared.
 - Making the algorithm $n^2$ seems to account for possible greediness.
