The first thing to do in this case is to draw the ordered pairs in the Cartesian plane and join the points. We have then that the resulting figure is a rectangle. We must find the perimeter of the rectangle that is given by: P = 2L + 2W Where, L: long W: width Restoring the values: P = 2 * (5) + 2 * (3) P = 16 Answer: her route cover 16 miles.
