Each week I will
post a maths challenge or activity which you can solve with
your family and friends. I will post the solution to
each challenge the following week.
The level of
difficulty will change from week to week.
I will give each activity a star grading from « to ««««« with the level of difficulty increasing
with the number of stars. This star grading
is simply a guide.
Here is the first
challenge:
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, she slips back 2.
Frustrated, she stops where she is for the 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?
(In a few days I will post a hint for you
to check that you are on the right track to the solution.)
Enjoy,
Sarah Hopkins
