The climber decided to climb Mount Elbrus, the height of which is 5642m.

The climber decided to climb Mount Elbrus, the height of which is 5642m. What is the air temperature at the top of the mountain if at the foot of it the temperature is 20 degrees.

For the correct solution of the problem, the following rule must be remembered: with a rise for every 100 meters, the air temperature drops by 0.6 ° C. This allows us to find out how many times the air temperature will change with rise. To do this, perform the following action:

5642 ÷ 100 = 56.42.

In this way,

56.42 × 0.6 = 33.8 ° С – the air temperature will drop.

We now have all the data to calculate the air temperature at the top of the mountain:

+20 – 33.8 = -13.8 ° C.

At the top of Mount Elbrus, the air temperature is -13.8 ° C.
