:: Wounded Soldiers ::

Four soldiers, of which three are wounded, need to cross a dangerous bridge at night time to escape their enemy. The bridge can support at most two soldiers at any one time. The soldiers have only one torch light which needs to be used during the crossing. The non-wounded soldier can cross the bridge in 1 minute, whilst the less lucky ones take 2, 5 and 10 minutes respectively. Whilst crossing the bridge the less wounded soldier would need to support his buddy, and thus, cross the bridge at his buddy's pace.

What is the shortest time they can reach the other side in?
