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 and costs $50 a mile to lay, the second section runs from point Q to point and costs $42 mile , the third runs from point R to point S and costs $38 a mile. Looking at the diagram below, you bee 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. P 2 Miles I MUL 10 miles X miles y miles
