Chris walk miles to reach the X on the boat and 6 miles X
Therefore, the time they took the sqrt (2 ^ 2 + x ^ is 2) / 3 + (6-X) / 6 = T (for example)
T must be minimal, with the derivation of first order and that = 0.
Solution is 2/sqrt X = (3).
It is the land of his boat in the distance X will be less time-consuming.
1.1547005391739 miles from the point of the coast to the village.
