A chipmunk scampers about collecting in its cheeks safflower seeds that the birds dropped from the feeder hanging overhead. Initially the little creature is at position vector r1x = 2.45 m and r1y = -2.13 m. After filling up, it runs to the hole at position vector r2x = -1.89 m and r2y = 4.37 m that leads to its underground nest. Find the components of the chipmunk\'s displacement vector for this expedition, ?rx and ?ry.
