they overlap and leave gaps
1-overlapping is wrong cuz 1 service will always be closer than another
2-gaps mean those people are outside of a market area which is wrong

1-range
2-threshold

14

whats the range of a service

the max distance people are willing to travel for a service

15

why are ranges irregular shaped

it only takes in where the place is closer than competitors.

like someone going to mcdonalds wants to go to the closest one.

16

retailers define range as

max distance 3/4 of customers are willing to travel

17

why is range hard to compute (time vs distance)

people describe how far they are going to travel in time rather than in distance so a circle will have to be drawn to express time and take into account travel time varies

what is the threshold

min # of people customers needed to support the service
