A solar power field is located on the south bank of a straight river that is 2 km wide. A power line is to be constructed from the solar field to an electric substation located on the north bank of the river 4 km east of the solar field. The cost of running the power line is $100,000/km overland and $200,000/km under the river. To minimize the cost of the power line, how much of the power line should be run overland?
