Question

The average rate of population growth between 2013 and 2015 is 0.35 million per year. If the population continues to grow at this rate what year will it reach 40 million?

Answer 1

2021.

Step-by-step explanation:

The average growth rate between 2013 and 2015 was 0.35. That means it was 0.35/2 = 0.175 per year.

To find in how many years it will reach 40 million:

(40 - 39.1)/0.175 = 5.14

As we can see, it will take 5.14 years for the population to increase from 39.1 to 40 millions.

That means, in 5 years the population will not reach 40 million, but until the end of the 6th year, the population will reach.

That means the population will reach 40 million in 2021 (2015 + 6).
