A bridge connecting two little towns is strictly guared by a soldier who sits in a cabin right in the middle of the bridge. He has instructions to send back anyone attempting to cross the bridge. Roger lives in one of the towns and wants to cross the bridge to see his sweetheart. He stands at the foot of the bridge and studies the movements of the guard to see if there is any way he can cross over safely. He notices the guard stands vigilantly outside his hut for 5 minutes and then goes into his hut for another 5 minutes before he comes out again. Roger estimates if he runs very quickly, he might just get halfway in the 5 minutes the guard is in his hut, but then the guard would surely see him and send him back. How does Roger get across safely?

Roger goes half way towards the guard (25% total bridge length) as the guard in going back into his hut.

In five minutes Roger can get halfway from the guard to the other side before the guard comes out.

Roger runs as far as he can until the gaurd starts to come back out of the hut. When he sees the gaurd coming out he turns around and starts walking back the way he came. Now the gaurd thinks he came from the other side and tells him to go back and Roger gets to his sweetheart.
