    In a school, three rings of a bell indicate recess time.
    Most of the students try to get from their classroom to the school yard before the third ring of the bell.

    There is a ten second interval between each ring.

    If two seconds are used to store their books...

    Question :
    How much time is available to reach the school yard before the third bell ?
