In reaching her destination, a backpacker walks with an average velocity of 1.48 m/s, due west. This average velocity results, because she hikes for 6.07 km with an average velocity of 3.29 m/s due west, turns around, and hikes with an average velocity of 0.791 m/s due east. How far east did she walk (in kilometers)?

The speed of sound in ice, water, and steam is shown. what best explains the speed of sound in different states of matter? sound travels fastest in ice because energy is easier to transfer when the molecules are close together. sound travels slowest in steam because the sound has to move around the gas molecules that are far apart. sound travels fastest in ice because the temperature of solids is always greater, so the heat transfers the sound energy. sound travels slowest in steam because the pressure is so great the sound cannot travel though the steam particles.
