Question 932951: EARTH SCIENCE In 1970, Russian geologists began drilling a
very deep borehole in the Kola Peninsula. Their goal was to reach a
depth of 15 kilometers, but high temperatures in the borehole
forced them to stop in 1994 after reaching a depth of 12 kilometers.
They found that the approximate temperature x kilometers below
the surface of the Earth is given by
T = 30 + 25(X – 3) 3 ≤X ≤12
where T is temperature in degrees Celsius. At what depth is the tem-
perature between 150° and 250°c, inclusive?
