The stadion, also known as the stade, was the standard short distance sprint in ancient Greece and ran the length of a stadium. However, stadiums could vary in size and there was apparently no definite standard length for them, e.g., the stadium at Delphi measures 177 m and the one at Pergamon 210 m.
The distance (or perpendicular distance) from a point to a line is the shortest distance from a fixed point to any point on a fixed infinite line in Euclidean geometry. It is the length of the line segment which joins the point to the line and is perpendicular to the line. The formula for calculating it can be derived and expressed in several ways.
A metric or distance function is a function d which takes pairs of points or objects to real numbers and satisfies the following rules: The distance between an object and itself is always zero. The distance between distinct objects is always positive. Distance is symmetric: the distance from x to y is always the same as the distance from y to x.
"Walk-back sprinting" is one example of interval training for runners, in which one sprints a short distance (anywhere from 100 to 800 metres), then walks back to the starting point (the recovery period), to repeat the sprint a certain number of times. To add challenge to the workout, each of these sprints may start at predetermined time ...
Dijkstra's algorithm starts with infinite distances and tries to improve them step by step: Create a set of all unvisited nodes: the unvisited set. Assign to every node a distance from start value: for the starting node, it is zero, and for all other nodes, it is infinity, since initially no path is known to these nodes.
The flights are always combined with flights from and to Kirkwall Airport (27 mi (43 km) distance), flying in a narrow triangle. [6] Pilot Stuart Linklater flew the short hop more than 12,000 times, more than any other pilot, before he retired in 2013. Linklater set the record for the fastest flight between the islands at 53 seconds. [5]
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. This distance is an element in solving the second (inverse) geodetic ...
The destinations listed can range from a short distance away, such as a few miles or kilometers, to long distances away, from several hundred or even thousands of miles or kilometers away. Unlike most road signs, mileage signs remain roughly consistent throughout the world, with the only differences being background colors on signs and the ...
