Question

When will the United States population double if it continues to grow at a rate of 0.60% per year?

A) In approximately 100 years
B) In approximately 120 years
C) In approximately 140 years
D) In approximately 160 years

Answer 1

The United States population will double in approximately 120 years if it continues to grow at a rate of 0.60% per year.

Step-by-step explanation:

To determine when the United States population will double, we need to use the rule of 70. The rule of 70 states that the doubling time can be found by dividing 70 by the growth rate as a percentage. In this case, the growth rate is 0.60%. So, the doubling time is approximately 70/0.60, which is around 116.7 years. Therefore, the United States population will double in approximately 120 years, which is option B.
