If I'm reading your description right, I think your first boat is heading up and to the right ("direction N.68 degrees E") making an angle of 68 degrees with north, or 22 degrees with east.  And I think your second boat is headed directly east ("S.90 degrees E").  So I'm assuming that they form a triangle, with one angle being 22 degrees and another one being a 90 degree angle, since we're looking for the point where one boat will be directly south of the other.\n\nThe first boat traveled 12t miles so far.  The second boat left an hour later and traveled 16(t-1) miles.\n\nThe first boat's path turns out to be the hypotenuse of the triangle, and the second boat's path will be one of the adjacent legs to the 22 degree angle.  So we can set up an equation with trig identities:\n\ncos 22 = 16(t-1)/12t\n0.9272 = 4(t-1)/3t\n2.7816t = 4t - 4\n4 = 1.2184t\nt = 3.3 hours\n\nSo after 3.3 hours, one boat will be directly south of the other.\n\nFinding that distance can be done one of several ways: using the Pythagorean theorem, sine relationships, law of cosines, etc.  I'll use sine, since we're already doing trig.  After 3.3 hours, the northernmost boat will have traveled 39.6 miles.  The distance between the boats becomes our side opposite the 22 degree angle.  So,\n\nsin 22 = distance between/39.6\ndistance = 39.6sin 22\n= 14.83 miles\n\nNow if I read the angle wrong, then simply go back and change all the "22" angles to the correct one and recalculate.

One is the grandfather, one is the father and one is the son. Grandfather and father are two dads, father and son are are two sons.

it mens when rivers don't take the normal course into the ocean but drain into a large lake away from the sea.

My father lives in Kinmount, ON (close to Minden/Haliburton), my brother and father are always going on little fishing trips on the weekends, I would try the Ox&Arrows lodge in Minden, if they can't help you they will know who can.

See what you think about this approach - \n\nInitially the COM of the system is at the 15 foot mark - the man's 200 lb COM is at 20 ft and the canoe's 200 lb COM is at 10 ft. Since you are neglecting friction between the canoe/man system and the environment, the COM of the canoe/man system can't change - change in COM would require some force, and there is no mechanism available to transmit any force. So that means at the end, the COM of the canoe/man system is at the same place relative to the pier as it was at the beginning - i.e. at the 15 foot mark. Since at the end the man is now at the end of the canoe nearest the pier, and the COM has to be at the 15 foot mark, the man must be at the 10 foot mark, and the far end of the canoe is at the 30 foot mark. Drawing a picture helps !!
