A long distance runner is in training for a 10 km race and is gradually getting closer to his target speed. His recent times over 10 km have consistently decreased each week. His times for the last five weeks have been 58m 20s, 56m 40 s, 55m 00 s, 53m 20 s and 51m 40 s. It is assumed that his improvement will continue at the same rate. With two more weeks of training remaining, how fast will he be likely to run in the actual race

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.
