How these distances are calculated
Straight-line figures are great-circle distances between incorporated-place centroids using the haversine formula on a 3,958.76-mile mean-radius sphere — exact to within a few metres for this purpose. Drive time is an estimate: road distance is modelled at 1.2× the straight line (the standard North American circuity factor) at 62 mph for trips over 60 miles and 35 mph below that. It is not a routed itinerary and ignores traffic, terrain and tolls.
