3. 10? Unless it's a trick question
4. 3, not counting the start.

EDIT: Wait - I think number 4 was a trick question. You didn't specify that there was a destination - So I don't think there is way of knowing, without saying that the third stop was the destination.

I might be too late but it should be around 20 since you write one six each sixties but two on sixty-six smile
