Question 3 • Mathematics III

A city’s bus line is used more as the urban population density increases. The more people in an area, the more likely bus lines will be utilized. The population of City A, in Texas, is 29 comma 455 and covers an area of 19 point 4 2 mi squared The population of City B, in Alabama, is 34 comma 890 and covers an area of 25 point 4 mi squared Which city’s residents are more likely to use public buses? Explain.

Answer
A
The residents of City B are more likely to use public transportation because the city has the lowest population density.
B
The residents of City B are more likely to use public transportation because the city has the highest population density.
C
The residents of City A are more likely to use public transportation because the city has the lowest population density.
D
The residents of City A are more likely to use public transportation because the city has the highest population density.

Explanation

Population density is population divided by area. City A’s density is about 29,455 ÷ 19.42 ≈ 1,517 people per square mile, while City B’s is about 34,890 ÷ 25.4 ≈ 1,374 people per square mile. Since City A has the higher population density, its residents are more likely to use public transportation.
