There's four stages in the classical demographic transition model:
Stage 1 - Pre-transition
In this stage, the birth rates are very high, but also the life expectancy is very low, thus the growth of the population is slow.
Stage 2 - Early transition
In this stage, the birth rates are very high, but the life expectancy is increased, so the population grows rapidly.
Stage 3 - Late transition
In this stage, the birth rates decline slightly, and the life expectancy is a bit higher, thus the population growth is slowing down.
Stage 4 - Post-transition
In this stage, the birth rates are declined significantly, the life expectancy is pretty high, so the population is either growing very slowly, or it is declining.
The basic units of length and volume are based in the metric system, good luck!
C average speed is used, which is total distance divided by total time.
Explanation:
From the analogy presented, we know that because the speed at which an object travels varies over time, the average speed is used.
The average speed is is the total distance traveled divided by the total time taken.
The average speed appropriately reflects changes in rate of speed with time.
It accounts for moments where a car slows and speeds up.
