Mt Everest is at the height of 8850 m and its base is at an elevation of 5400m. The temperature here drops at the rate of 1°C per 100m. If temperature at the base is –5°C. What will be the temp at the top?

Elevation between the top of Everest and Base of Everest = 8850 – 5400 = 3450 m

Given: For every 100 m temperature decrease by 1°C

For Every 1 m, Decrease in Temperature

For 3450 m, Decrease in temperature

So, the decrease in temperature from Base to top of Everest = 34.50°

Temperature at Base = – 5° C

Temperature at top = Temperature at Base – (Decrease in temperature from base to top)

Temperature at top = – 5° – 34.50°

Temperature at top = – 39.50° C
