Question

the world population at the beginning of 2008 was 6.7 billion and growing at a rate of 1.16% each year. When will the population double the 2008 population?

Answer 1

The world population of 6.7 billion in 2008 is expected to double in approximately 62 years, around the year 2070, based on an annual growth rate of 1.16%, using the Rule of 72.

Step-by-step explanation:

The student has asked when the world population will double from its 2008 level of 6.7 billion, given an annual growth rate of 1.16%. To solve this, we will use the Rule of 72, a simple way to estimate the number of years required to double the population at a constant annual growth rate. The formula is 72 divided by the growth rate. So in this case, it would be 72 / 1.16, which equals approximately 62.07. Therefore, it will take roughly 62 years from the beginning of 2008 for the world's population to double, assuming a steady growth rate of 1.16%. This would project the doubling to occur around the year 2070.
