Hello everyone! I would like to know if this is a good approach when finding the number of gas stations in Chicago:
I would start by finding the # of cars in Chicago divided the number of cars per gas station.
To find the # of cars in Chicago at a given day I would multiply the number of households x the number of cars per household. To find the number of households I would divide Chicago population by # of people per household. In that order:
Chicago population 3 m aprox.
# people per household 3
# cars per household 1
# cars in chicago = 1M
To find the number of cars per gas station per day I would start finding the capacity per gas station x utilization rate x hours open. In that order:
Capacity = 4 (4 pumps on average)
Utilization rate = 50%
Hours open = 24 h
# Cars per gas station per day = 2 x 24 = 48
# Gas stations in Chicago = 1 M / 48 = 21000 aprox.
I am not sure if this approach is good since my number is way higher than the current one. Do you know where is the mistake?
Thank you very much
