As this problem is worded, printed, posted, and presented, it is posed INCORRECTLY, and in this form CAN NOT be solved.
There is a very close (but different) formulation, where this problem becomes nice and can be solved in amazingly perfect way.
To see this formulation and to learn the subject/(the solution), look into my lesson
- A rabbit and a dog
in this site.
As I see from this post, a person who created/composed the problem, had heard once something similar to correct formulation,
but was not able to bring it intact.
Do not forget to post your "THANKS" to me for my teaching.
