A variation of a triathlon competition has a contestant swimming from a point, A, on one shore of a lake, to a point C on the opposite parallel shore, then running to the finish, B, further along the lakeshore. The lake is 4km wide and the finish line is 10km down the lake. If a contestant can swim at 2km/h and run at 10km/h, determine the point C that will minimize the total time for the race.
Thank you =D
