Although units of length are normally most appropriate for measuring distance
, with urban congestion
taking over more and more of people's living space we often refer to distance in units of time
. In the Los Angeles
area, this has been true for years:
"How far is it from here to your grandmother's house?"
"About 40 minutes."
In San Francisco
, it takes me about 20 minutes to get between any two points. If they're close together, I walk. If they're far apart, I ride my motorcycle or take a taxi.
