Sure it’s great to have a conversation about the important things on our minds
…but it’s also fun to put those minds to work!
Check back to the comments section to see a list of men who solve the puzzle. Can you be the first with the solution? All men who solve the puzzle will also be listed when we publish the next puzzle and be recognized at the FJMC International Convention in Massachusetts, July 2013
THIS MONTH’S PUZZLE:…suggested by Ken Turkewitz
There are four men on one side of a cavern needing to get to the other side. They must cross an old rope bridge. No more than two can cross at any one time. They have a lantern and they must carry the lantern with them whenever anyone crosses.
It takes man A 10 minutes to cross.
It takes man B 7 minutes to cross.
It takes man C 2 minutes to cross.
It takes man D 1 minute to cross.
When two men are traveling together, they travel at the speed of the slower man.
There is no other way to get across than to use this bridge.
What is the minimum amount of time it can take for all four men to get across the cavern?
Try to solve the puzzle. And, when you do, send the answer along with your synagogue and city and get your name listed in next month’s issue.
