Anne rode 3000 m east. she then turned and rode 2000 m to the west in 1000 seconds. what was her velocity?

1m/s [E]

Explanation:

So for displacement, its saying she went 3000m east and 2000m west. Since these two are in different directions, you would change the sign of one of them to change the direction;

3000m [E] + 2000m [W] = d

3000m [E] - 2000m [E] = d

1000m [E] = d

And its saying the time is 1000 seconds, so using velocity formula:

v = d/t

v=1000m[E] / 1000s

v = 1 m/s [E]

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
