So, for example, if a route is 20 kilometres (12 mi) with 1600 metres of climb (as is the case on leg 1 of the Bob Graham Round, Keswick to Threlkeld), the equivalent flat distance of this route is 20+(1.6×8)=32.8 kilometres (20.4 mi). Assuming an individual can maintain a speed on the flat of 5 km/h, the route will take 6 hours and 34 minutes.
In his original book, Cooper also provided an alternate version of the test, based on the time to complete a 1.5 mile run. [1] Most armies and police agencies of the world use a fixed distance. This is not exactly a Cooper test but a reasonable practical compromise as long as the distance is of sufficient length to put a continuous load on the ...
The first equation shows that, after one second, an object will have fallen a distance of 1/2 × 9.8 × 1 2 = 4.9 m. After two seconds it will have fallen 1/2 × 9.8 × 2 2 = 19.6 m; and so on. On the other hand, the penultimate equation becomes grossly inaccurate at great distances.
The speed of sound is the distance travelled per unit of time by a sound wave as it propagates through an elastic medium. More simply, the speed of sound is how fast vibrations travel. At 20 °C (68 °F), the speed of sound in air, is about 343 m/s (1,125 ft/s; 1,235 km/h; 767 mph; 667 kn), or 1 km in 2.91 s or one mile in 4.69 s.
The world record in the mile run is the fastest time set by a runner in the middle-distance track and field event. World Athletics is the official body which oversees the records. Hicham El Guerrouj is the current men's record holder with his time of 3:43.13, [1] while Faith Kipyegon has the women's record of 4:07.64. [2]
is the distance over which the initial time is achieved D 2 {\displaystyle D_{2}} is the distance for which the time is to be predicted Riegel expanded on his thesis in a 1981 article for American Scientist , stating that the formula t = a x b {\displaystyle t=ax^{b}} concerns activities in the "endurance range", namely lasting between 3.5 and ...
The Beyer Speed Figure is calculated by looking at the final time and distance of the race, adjusted by the track variant, which is a measure of the inherent speed of the racetrack in question. The track variant considers both the historical average time at the racetrack for the distance in question, called the "par time", and the average speed ...
Different from instantaneous speed, average speed is defined as the total distance covered divided by the time interval. For example, if a distance of 80 kilometres is driven in 1 hour, the average speed is 80 kilometres per hour. Likewise, if 320 kilometres are travelled in 4 hours, the average speed is also 80 kilometres per hour.
