Final answer:
The population of Brookmarsh is currently 10,000 and increasing at a rate of 2%. Using the rule of 70, we can estimate how long it would take for the population to reach 14 billion.
Step-by-step explanation:
The question pertains to population growth in the town of Brookmarsh. The population is currently 10,000 and is increasing at a rate of 2%.
To calculate how many years it would take for the population to reach 14 billion, we can use the rule of 70. The rule of 70 states that the doubling time for a given growth rate can be found by dividing 70 by the growth rate.
So, for a growth rate of 2%, the doubling time is 70/2 = 35 years. Since it took 260 years for the population to reach 7 billion, we can estimate that it would take another 35 years for it to reach 14 billion.
