28/01/2013 - Bridge Walk (**)

This puzzle is rated 2 star (medium).


A group of 4 people are walking through the jungle and come across an old wooden bridge.

It is dark and they only have one torch between them all, and they need to light the path when crossing the bridge.

Unfortunately, as it is an old bridge, no more than 2 people can walk on the bridge at any one time - otherwise it will collapse.

Some walkers are faster than others at crossing the bridge:
  • Amie takes 1 minute to cross
  • Ben takes 2 minutes to cross
  • Clare takes 5 minutes to cross
  • Dean takes 10 minutes to cross

Have all four people cross the bridge in the quickest time possible.

Check the solutions page for the correct solution.
