An isolated farm house is located on the bank of a straight canal that is 200 m wide. Electric power for the house must come from a connection that is on the opposite side of the canal, 500 m downstream. If the cost to lay cable underwater is three times the cost of laying on land, what path should be chosen to minimize cost?
