Suppose about 400,000 people live in an area of 160 square miles. what is the best estimate for the population density? a) 1,800 people per square mile b) 2,000 people per square mile c) 2,200 people per square mile d) 2,500 people per square mile

2,500 people per square mile

Step-by-step explanation:

Population density is calculated by : Population / square miles

Therefore :

Population density = 400,000/160

                                = 2,500

D)

2,500 people per square mile

Step-by-step explanation:

To calculate density of a population;

Population Density = Number of People / Land Area

= 400,000 / 160

= 2, 500

= 2,500 people per square mile

step-by-step explanation:
