Suppose about 400,000 people live in an area of 160 square miles. What is the best estimate for the population density?

2500 people PER square mile

Step-by-step explanation:

THe population density is the population per unit area.

Here,

Given:

Population = 400,000

Total Area = 160 sq. miles

To get population density, we would need the population PER UNIT AREA, per miles.

We can get that by dividing the total population by total area:

400,000/160 = 2500 people PER square mile

This is the population density.
