Question

As of early 2014, the world's population was about 7.2 billion people. The population of the United States was 317 million.

The land area of the state of Texas is about 261,797 square miles. If in early 2014 all the world's people were put into Texas, how many people would there be in each square mile? Round your answer to the nearest whole number.

Answer 1

7.2 billion people/(261,797 mi²) = (7,200,000,000 people)/(261,797 mi²)

 

                                             = 27,502.255 people/mi²

 

                                             ≈ 27,502 people/mi²
