Answer:

30meter per second

Explanation:

Given that

Distance = 3000 meters

Time = 100seconds

Speed = distance /time

Substituting the values

Speed = 3000/100

Speed = 30meter per second

The average speed needed to cover the travelling will be 30meter per second.

Temperature Control

Another important aspect of air is that it helps in maintaining the temperature on the earth surface by circulating hot and cold air. Air acts as a conductor of heat as well. Even phenomena such as water cycle are dependent on air.

Supplier of Energy

Air which consists of energy is one of the main suppliers of energy. Living things are made up of cells and these cells extract oxygen within the blood to produce energy usually in the form of ATP. This biochemical generation of ATP is essential to maintain life on the earth.

Photosynthesis

Carbon dioxide, which is a component of air is used by plants during the process of photosynthesis. Here oxygen is also released by plants. And we already know how vital oxygen is.
