In drilling world's deepest hole it was found that the temperature T in degree celcius, x km below the earth's surface was given by T = 30 + 2.5 (x -3), 3 ≤x≤15. It was assumed that this drilling resulted 5% increase in carbon dioxide level at a temperature above 205∘ and below 155∘C, so drillers tried to control the depth between these two limits. At what depth will the temperature be between 155∘ and 205∘ What values are depicted here by the drillers for selecting this temperature range ? |
