Question 1163671: A dog finds a rabbit 10 meters away from it, and it starts chasing. Every 5 steps the dog runs is the same as 9 steps the rabbits runs, but the time for the dog to run 2 steps, the rabbits can run 3 steps. How many meters does the dog need to run to catch up with the rabbit?

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.
