Question

If a population roughly doubles in the course of 50 years, its growth rate would be close to ________%.

Answer 1

Answer:

The correct answer would be, 1.5% approximately.

Explanation:

If a population roughly doubles in the course of 50 years, then its growth rate would be close to 1.5%.

If the population is 10000 in year 1, In 50 years if it increases with the rate of 1.5%, the population  after 50 years would be calculated as follows:

10000*1.5%=10000*0.015= 150

It means there will be an increase of 150 people in the population every year. So after 50 years, there would be an increase of 7500 in the original population of 10000 which is roughly close to the double of the original population.
