Riddle 8 Solution: Burning at Both Ends
by William Jackson on 2009-10-29
Jared solved the riddle first:
light the first rope at both ends and light the second rope at one end. when the first rope has burned up (in 30 min.), light the other end of the second rope. It will burn up in 15 min. 30 min + 15 min. = 45 min.
Sarah, Iʼm afraid your solution wonʼt work, because you are still independently measuring fifteen minutes somehow. If you had a watch, the entire riddle would be moot.
