Question

Mt Everest is at a height of 8850m. Its base is at an elevation of 5400 m. The temperature drops at a rate of 1°c per 100 m. If the temperature at the base is 5°c, what is the temperature at the top.

Answer 1

The height of Mount Everest above the base =  8, 850 - 5, 400 = 3, 450 meters

If there is a temperature drop of  1 deg. C, per 100 meters, then there is a drop of  3450/100 = 34.5 deg C, to th peak.

so the temperature at the peak is 5 - 34.5 = - 29.5 deg C.
