In reaching her destination, a backpacker walks with an average velocity of 1.31 m/s, due west. This average velocity results, because she hikes for 6.93 km with an average velocity of 2.06 m/s due west, turns around, and hikes with an average velocity of 0.688 m/s due east. How far east did she walk (in kilometers)?
