Question

the least densely populated state in a country is state A, with 1.2 people per square miles. Tourists from a different country are planning their travels through state A. They are familiar with kilometers as a frame of reference. To help the tourist better relate to the measurements, convert the population density to people per square kilometer

Answer 1

1.93 km would be 1.2 m 

Answer 2

0.47 people per square km

Explanation:

Given,

Population density = 1.2 people per square miles

which mean that no. of people living in one square mile area = 1.2

We know that, 1 mile = 1.6 km

Thus, one square mile = (1.6)² square km = 2.56 square km

So, no. of people living in 2.56 square km area = 1.2

Thus, no. of people per square km is

`= (1.2)/(2.56)`

= 0.47

Thus population density is 0.47 people per square km.
