He goes 5km to the stream.Now he is 5+6 km North of his cabin and 8 km east.apply pyth -> sqrt(11^2+8^2)He travels sqrt(185)+5 ~= 18.6

The trench is 5m x 5m which makes a Single lane road for 10 meters (2.5 meters on either side of the trench for Maneuvering). As the driving discipline and etiquette of indian rivers is World famous they allow five cars from one lane and then five cars from The other lane to enter the single lane portion of the road.
