Given :
The temperature of Pokhara lying at an altitude of 900 m is 20 degree Celsius.
To Find :
The temperature of MT Everest base camp lying at an altitude of 6000 m.
Solution :
Let, temperature at 6000 m height of MT Everest is T.
So, by proportionality constant :
Therefore, the temperature of MT Everest base camp lying at an altitude of 6000 m is 3°C .
