    Light one wire at one end and the other at both ends.
    After 30 minutes the wire that is burning at both ends will be burned completely (1 hour/2).
    The other wire will have 30 minutes remaining.
    Now light the other end of that wire.
    After another 15 minutes (30/2) that wire will also be burned completely.
    Total time 45 minutes (30 + 15)
