A runner dashes 263m in a direction due North from the starting line (Xi = 0m). She then turns around and runs due South back toward the starting line 62m. If both legs of this run take a total of 203 seconds, to the nearest tenth of a m/s, what is her average velocity?

i think the answer would be reserve.

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.
