Question

A town with a population of 80,250 people has 500 city blocks. Each block is one-tenth mile long by one-tenth mile wide. Find the population density of the town in the people per square mile.

Answer 1

First, we need to find the area of one block:

Area of one block = length x width = (1/10) mile x (1/10) mile = 1/100 square mile

Since there are 500 blocks in the town, the total area of the town is:

Total area of town = 500 blocks x (1/100) square mile/block = 5 square miles

To find the population density, we divide the population by the total area:

Population density = population / total area

Population density = 80,250 / 5 = 16,050 people per square mile

Therefore, the population density of the town is 16,050 people per square mile.
