I would think so because when you add up their times, 1 + 2 + 4 + 5 = 12...but that doesn't include thier going back and forth to hand off the torch, right? So no, it wouldn't really work, unless the torch could fly between them...



you are wrong because say 4+5 went together...it didnt take 9 minutes it only took 5....the answer is that the fastest they could have done it in is 13 minutes so they fail...

1+5 went = 5 minutes
1 went back = 6 minutes
1+4 went = 10 minutes
1 went back = 11 minutes
1+2 went = 13 minutes

the quickest way is ALWAYS going to be with 1 being the one going back...so therefore it is impossible

what of they went in a diamond pattern. 2 in front (the fastest), 1 in the middle (the brother, 4 minuets) and the sister behind the brother and the brother holds the torch high so that the light can be distributed over the runners.

they were right in saying they could successfully complete the trip in the twelve minutes. just because 1 minute is the lowest value doesnt mean its necessarily the most time conservative to have that person go back and forth each time.

if mom and dad are left alone, it could lead to some more loss of time, better be careful

It's sort of Old English, but it's grammatically correct.

Think of it like this: through the tight tunnel, can go, at once, not more than two persons. Some pauses are required to get the meaning of the sentence.


so the tunnel is just tight, meaning that only 2 can walk abreast. but why cant they walk in rows of two? there is nothing to suggest that they couldnt. of course im sure its much more complex than just that, but part of riddles is looking outside the box. if it were a flashlight, they could roll it back through the tunnel to the next set
