Pace [6] in minutes per kilometre or mile vs. slope angle resulting from Naismith's rule [7] for basal speeds of 5 and 4 km / h. [n 1] The original Naismith's rule from 1892 says that one should allow one hour per three miles on the map and an additional hour per 2000 feet of ascent. [1] [4] It is included in the last sentence of his report ...
A four-minute mile is the completion of a mile run (1.6 km) in four minutes or less. It translates to a speed of 15 miles per hour (24 km/h). [1] It is a standard of professional middle distance runners in several cultures. The first four-minute mile is usually attributed to the English athlete Roger Bannister, who ran it in 1954 at age 25, in ...
A nautical mile is a unit of length used in air, marine, and space navigation, and for the definition of territorial waters. [2] [3] [4] Historically, it was defined as the meridian arc length corresponding to one minute ( 1 / 60 of a degree) of latitude at the equator, so that Earth's polar circumference is very near to 21,600 nautical miles (that is 60 minutes × 360 degrees).
On May 6, 1954, Roger Bannister, a 25-year-old medical student, worked his usual morning shift at St. Mary’s Hospital and took an afternoon train from Paddington Station to Oxford in preparation ...
For a performance to be ratified as a world record by World Athletics, the marathon course on which the performance occurred must be 42.195 km (26.219 mi) long, [34] measured in a defined manner using the calibrated bicycle method [35] (the distance in kilometers being the official distance; the distance in miles is an approximation) and meet other criteria that rule out artificially fast ...
A 155-pound person burns about 360 calories in 30 minutes of running at a 10 minute/mile pace, according to Harvard Medical School. Run a single mile at that pace and you'll burn about 120 calories.
The knot (/ nɒt /) is a unit of speed equal to one nautical mile per hour, exactly 1.852 km/h (approximately 1.151 mph or 0.514 m/s). [1][2] The ISO standard symbol for the knot is kn. [3] The same symbol is preferred by the Institute of Electrical and Electronics Engineers (IEEE), while kt is also common, especially in aviation, where it is ...
Geographic coordinate conversion has applications in cartography, surveying, navigation and geographic information systems. In geodesy, geographic coordinate conversion is defined as translation among different coordinate formats or map projections all referenced to the same geodetic datum. [1] A geographic coordinate transformation is a ...
