In reaching her destination, a backpacker walks with an average velocity of 1.14 m/s, due west. This average velocity results, because she hikes for 5.56 km with an average velocity of 3.44 m/s due west, turns around, and hikes with an average velocity of 0.376 m/s due east. How far east did she walk (in kilometers)? West East 3p Number Units km
