On the mountainside, at an altitude of 1700m, the air temperature is -5.

On the mountainside, at an altitude of 1700m, the air temperature is -5. What is the air temperature at the foot of the mountain, located at an altitude of 350m

1) Find the difference in heights on the mountainside and at the foot.

1700 m – 350 m = 1350 m.

2) It is known that with an ascent for each kilometer, the air temperature drops by 6 ° C.

Let’s find a decrease in temperature in this area.

1350 m = 1.35 km.

1.35 km * 6 ° C = 8.1 ° C.

3) Find the air temperature at the foot of the mountain. To do this, add the temperature decrease during the ascent to the air temperature on the slope.

8.1 ° С + (-5 ° С) = 3.1 ° С – air temperature at the foot.

Answer: 3.1 ° C.
