In the Euclidean TSP (see below), the distance between two cities is the Euclidean distance between the corresponding points. In the rectilinear TSP, the distance between two cities is the sum of the absolute values of the differences of their x- and y-coordinates. This metric is often called the Manhattan distance or city-block metric.
Biblical mile (Hebrew: מיל, romanized: mīl) is a unit of distance on land, or linear measure, principally used by Jews during the Herodian dynasty to ascertain distances between cities and to mark the Sabbath limit, equivalent to about ⅔ of an English statute mile, or what was about four furlongs (four stadia).
The distance between two points in physical space is the length of a straight line between them, which is the shortest possible path. This is the usual meaning of distance in classical physics, including Newtonian mechanics. Straight-line distance is formalized mathematically as the Euclidean distance in two- and three-dimensional space.
Geographical distance or geodetic distance is the distance measured along the surface of the Earth, or the shortest arch length. The formulae in this article calculate distances between points which are defined by geographical coordinates in terms of latitude and longitude .

English Channel. / 50.2; -2. The English Channel, [a] [1] also known as the Channel, is an arm of the Atlantic Ocean that separates Southern England from northern France. It links to the southern part of the North Sea by the Strait of Dover at its northeastern end. It is the busiest shipping area in the world. [2]
Dijkstra's algorithm ( / ˈdaɪkstrəz / DYKE-strəz) is an algorithm for finding the shortest paths between nodes in a weighted graph, which may represent, for example, road networks. It was conceived by computer scientist Edsger W. Dijkstra in 1956 and published three years later. [4] [5] [6]
Just east of I-29 is where I-90 meets the northern terminus of I-229. East of Brandon and northeast of Valley Springs, it then ends its trip through South Dakota of 413 miles (665 km) before entering Minnesota and Rock County, just west of the towns of Beaver Creek and Manley . Since April 2015, the speed limit is 80 mph (130 km/h) between the ...
