## Homework Statement

10. In reaching her destination, a backpacker walks with an average velocity of 1.34 m/s, due west. This average velocity results because she hikes for 6.44 km with an average velocity of 2.68 m/s, due west, turns around, and hikes with an average velocity of 0.447 m/s, due east. How far east did she walk?

## Homework Equations

## The Attempt at a Solution

2.68 m/s

^{2}= 6.44 km/t

_{w}

.447 m/s

^{2}= D

_{e}/t

_{e}

Avg V = (X - X

_{0})/(t - t

_{0})

The answer is 0.81 km, but I can't figure out how to solve this.
