Calculate the temperature in the mine if the surface of the earth is + 8 degrees and the depth of the mine is 750 m.

Since for every 100m of depth there is an increase of + 3C, then:
1) 750/100 = 7.5 (since 100m)
2) 7.5 * 3 = 22.5C ° – this is how much the temperature will rise.
3) 22.5 + 8 = 30.5C ° -temperature in the mine.
Answer: 30.5С °
