The rabbit problem

The Rabbit Puzzle A rabbit falls into a dry well 30 metres deep. Since being at the bottom of a well was not her original plan, she decides to climb out. When she attempts to do so, she finds that after going up 3 metres (and this is the sad part), she slips back 2. Frustrated, she stops where she is for that day and resumes her efforts the following morning – with the same result. How many days does it take her to get out of the well?
