Guest Posted March 12, 2008 Report Share Posted March 12, 2008 There are three people needing to cross a gap of ice. It takes three minutes for one person to cross at the highest possible speed. The ice can support only one person at a time. The ice will melt in eight minutes. They wait for the ice to melt then swim the gapHow do they get across?

0 bonanova Posted March 14, 2008 Report Share Posted March 14, 2008 OP says.. There are three people needing to cross a gap of ice. The posted solution does not work.If they wait for the ice to melt, there won't be a gap of ice to cross Quote Link to comment Share on other sites More sharing options...
0 Guest Posted March 16, 2008 Report Share Posted March 16, 2008 I agree with puzzled. Hypothermia would set in quickly and they wouldn't make it across. (unless you count "waiting for the ice to melt" as waiting for summer). I say the solution is they go in order of fastest to slowest and say good luck to the last person. That or fight it out and the winner runs across. Quote Link to comment Share on other sites More sharing options...
