The population density of earth refers to the number of people per square mile of land area. If the total land area on earth is $5.751 \times 107$ square miles and the population in 2007 was estimated to be $6.67 \times 109$ people, then calculate the population density of earth at that time.

Negative Exponents
The Earth's population is approximately $7.3 \times 10^{9}$ people, and there are approximately $1.5 \times 10^{8}$ square kilometers of land on the surface of the Earth. If one square kilometer is approximately 247 acres, how many acres per person are there on Earth? Round to the nearest tenth of an acre.
