An oil refinery is located on the north bank of a straight river that is 2km wide. A pipeline is to be constructed from the refinery to the storage tanks located on the south bank of the river 6km east of the refinery.
The cost of laying pipe is $400,000/km over land to a point 'P' on the north bank and $800,000/km under the river to the tanks. To minimise the cost of the pipeline, where should 'P' be located?
