The population density of City A is 6000 people per square mile. City B is a dilation of City A with scale factor 1.5 . If City B has 3/5 of the population of City​ A, what is the population density of City​ B?

Step-by-step explanation:

Number of people per square mile in City A is 6000.

In terms of size City B is a dilation of City A with scale factor 1.5.

This means a length of 1 mile in city A would be 1.5 miles in city B.

So,

City B has of the population of City​ A.

So the population density of City B would be

The population density of City​ B is .

so, converting firstly the mixed fractions to improper fractions and then "adding".
