In reaching her destination, a backpacker walks with an average velocity of 1.22 m/s, due west. This average velocity results because she hikes for 6.44 km with an average velocity of 2.53 m/s, due west, turns around, and hikes with an average velocity of 0.445 m/s, due east. How far east did she walk?
Can someone please help me please? I really really need help on this please!!!!
