brain teaser....chrck i out
Four members of a band are walking to a night concert. They decide to take a short cut, but must cross a bridge. Luckily they have one flashlight. Because of the varying size of there instruments, it takes each member a different amount of time to cross the bridge - it takes the 1st person one minute, the 2nd person 2 minutes, the 3rd person 5 minuutes and the 4th person 10 minutes. They must cross the bridge in pairs, traveling at the lower speed so if the one minute person went with the 10 minute person it would take a total of 10 minutes. Since there is only one flashlight, one person must come back across the bridge, then another pair can cross. They have only 17 minutes to cross the bridge and still get to the concert on time. what order should they cross to get everyone across and get to the concert?!?!?!?!
I cant figure it out...can any one get this?
