Thanks for the feedback. I'm impressed that that approach worked!

Really loved this one. I'm guessing I made a lot harder than I had to. I solved it by defining the infintesimal chance the boy caught the bus in a moment of time dt and integrating over the full window. No geometry for me lol.

I'm very happy with having solved this kata. This was the first time I've implemented depth first search.
I really feel like I'm applying the ideas of graph traversal. Also I think this is my first 2 kyu kata.

Think about it a little broader... The listed times were an hour and 15 minutes and 59 seconds, 1 hour 47 minutes and16 seconds, etc... These represent a definite time value. One length of time. If you want to do statistics on these times, it isn't going to work to break them into partial times.
