Answer 1

The number of more people per square mile living in Detroit compared to Grand Rapids is approximately 400.45 people per square mile.

Step-by-step explanation:

To find the number of more people per square mile living in Detroit versus Grand Rapids, we need to find the population density for each city. Population density is calculated by dividing the population by the area. Let's do the calculations:

Detroit population density = Detroit population / Detroit area = 672,800 / 142.9 = 4,706.42 people per square mile

Grand Rapids population density = Grand Rapids population / Grand Rapids area = 195,100 / 45.3 = 4,305.97 people per square mile

To find the difference in the number of people per square mile, we subtract the population density of Grand Rapids from the population density of Detroit. Therefore, the number of more people per square mile living in Detroit compared to Grand Rapids is approximately 400.45 people per square mile.

Answer 2

401 people per square mile

Step-by-step explanation:

First find the number of people per square mile in Detroit by dividing people by square miles:

672,800/142.9 = 4708.18754374

Then do the same for Grand Rapids:

195,100/45.3 = 4306.84326711

Subtract:

4708.2-4306.8 = 401.4

Round to the ones place:

401
