#17839 Crossing a bridge

Posted by glennsatur on 27 March 2008 - 08:25 AM

Nice job!


Answer is 12 minutes

Step 1 : Let the 10 mins guy start crossing...
Step 2 : After 5 minutes, let the 5 minute guy start..they reach the end at the same time
Step3 : Let the 2 minutes guy start
Step 4 : After a minute, let the one minute guy start...they reach at the same time..so in total 12 minutes
