Question 15
The park map uses green circles for trees and brown segments for paths. Each tree has a letter label.
Alex and Bob record the tree labels they pass:
Alex: B A A A C E D E E D A.
Bob: F D C D A E A D E D A.
They start simultaneously and each takes the same amount of time to traverse any one path segment. How many times do they meet?
