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
Thank you very much Antonello :)
