Question

Tokyo, Japan covers an area of 845 square miles. There are 38 million people living in Tokyo. Delhi, India has an area of 573 square miles and has a population of 36 million people. Although more people live in Tokyo, the population density is greater in Delhi. How many more people per square mile live in Delhi?

Answer 1

(36,000,000 / 573) - (38,000,000 / 845) = 17856.8 ≈ 17857 people per square mile

Answer 2

17857 people per mile²

Explanation:

Area of Tokyo, Japan = 845 square miles

Population Tokyo = 38 million

Area of Delhi, India = 573 square miles

Population of Deli = 36 million

Population density of Tokyo =
`(38)/(845)` = 0.04497 millions/miles²

Population density of Delhi =
`(36)/(573)` = 0.062827 millions/miles²

Difference in population density of Delhi and Tokyo = 0.062827 - 0.04497

= 0.17857 million per mile²

or 17857 people per mile² is the answer.
