An engineer is designing a pipeline which is supposed to connect two points P and S. The engineer decides
to do it in three sections. The first section runs from point P to point Q, and costs $48 per mile to lay, the
second section runs from point Q to point R and costs $54 per mile, the third runs from point R to point S
and costs $44 per mile. Looking at the diagram below, you see that if you know the lengths marked x and y,
then you know the positions of Q and R. Find the values of x and y which minimize the cost of the pipeline.
Please show your answers to 4 decimal places.
