2) Law of Retail Gravitation explains how large cities have greater drawing power
than smaller ones. See page 70 for
Reilly's equation of the "breaking point" between cities. Solve this:
Calculate the breaking point
for 2 cities (30 miles apart) where P1 has a population of 100,000 and P2 has a
population of 60,000. Use the equation
from the book and determine at what “mile” the breaking point would occur. Where would someone shop (which city) at a
certain distance from a city- 10 miles, 20 miles, etc.
3) Explain
how the concept of Retail Gravitation works in relation to the gravity model
and distance decay. How does a person’s
Time-space prism figure into these decision?
