Reilly's law states that the size of a city's hinterland (the area from which it draws people and resources) is proportional to the city's population raised to the 0.5 power. Therefore, the distance from which a city with 90,000 population draws people would be:
(90,000/10,000)^0.5 = 3
This means that a city with 90,000 population would draw people from about 3 times the distance as a city with 10,000 population. Therefore, the correct choice is C) 3 times.
