Question 15 • Geometry

The more people living in an area, the more likely it is that public buses will be used. City A has a population of 51 comma 242 and covers an area of 89 point 2 2 mi squared City B has a population of 50 comma 178 and covers an area of 8 point 1 2 mi squared Which statement about use of public buses in the cities is most likely true?

Answer
A
The residents of both cities are unlikely to use public buses because both population densities are too high.
B
The residents of City B are more likely to use public buses because their city has a greater population density.
C
The residents of both cities are equally likely to use public buses because both population densities are about the same.
D
The residents of City A are more likely to use public buses because their city has a greater population density.

Explanation

Population density is population divided by area. City A’s density is about 51,242 ÷ 89.22 ≈ 574 people per square mile, while City B’s is about 50,178 ÷ 8.12 ≈ 6,179 people per square mile. City B has the greater population density, so its residents are more likely to use public buses.
