Unless one is familiar with the puzzle, one needs more info on it to work it out for you.
If you are looking for an answer,it is best to ask the question.

If it is the answer is 17 minutes

1. The two fastest cross (elapsed time 2 minutes)
2. The fastest comes back with the torch (1 minute) - elapsed time now 3 minutes
3. Hands torch to the two slowest who cross (10 minutes) - elapsed time now 13 minutes
4. Hands torch to the second fastest who is already on the other side and he returns (2 minutes) - elapsed time 15 minutes
5. Two fastest cross (2 minutes) - elapsed time 17 minutes

The secret is to get the two slowest rabbits to cross at the same time!

Now if your puzzle is not a rewording of that one, then I guess it is necessary for you to tell us which one it is!
Crikey!
If rabbits eat a lot of carrots,why would they need a torch?
