<span>B) Hermitville by a factor of 1.19 Let's see by what percentage Hermitville increased it's population: (186480 - 142340)/142340 = 44140/142340 = 0.310102571 = 31.0102571% Since 31% is greater than 26%, that means that Hermitville is growing faster. Now by what factor? For that, we can simply divide the larger value by the smaller, so: 31.0102571 / 26 = 1.192702197 And looking at the available optoins, option "B" matches.</span>

The rate of increase of population of Hermitville is given by:
PR=(Present Population-Past Population)/(Past population)*100
PR=(186480-142340)/142340×100
PR=31.01%
The population increase in Hermitville is 31.01;
This implies that it's population growth is faster than that of Crabville by a factor of
31.01/26=1.19.
The answer is B
