The task of the cords

    Simple task. Sometimes I offer an interview :)

    There are two bikford cords. Different. One thing is known: each of them completely burns out in exactly an hour. How to measure 45 minutes using these cords (and lighters :)?

    Addition How the cords burn is not known: it can evenly, but maybe not.

    I will say it again. Just because a cord completely burns out in an hour does not mean that half the cord will burn out in 30 minutes.
