Kincheloe flew 2000 miles per hour (3,200 km/h) at 126,000 feet (38,500 m), or 24 miles up. At this altitude and speed, aerodynamic lift still carries 98 percent of the weight of the plane, and only two percent is carried by inertia, or Kepler force, as space scientists call it. But at 300,000 feet (91,440 m) or 57 miles up, this relationship ...
Mauna Loa (4,169 m or 13,678 ft) is the largest mountain on Earth in terms of base area (about 5,200 km 2 or 2,000 sq mi) and volume (about 42,000 km 3 or 10,000 cu mi), although, due to the intergrade of lava from Kilauea, Hualalai and Mauna Kea, the volume can only be estimated based on surface area and height of the edifice.
Although most contemporary accounts used an Arabic mile of 6 444 feet (1,964 metres), which gave a Spanish league of the degree of 25,776 feet (7,857 metres or 4.242 modern nautical miles) others defined an Arabic mile as just 6,000 feet making a Spanish league of the degree 24,000 feet (or 7,315 metres, almost exactly 3.95 modern nautical miles).
Many people tend to walk at about 1.42 metres per second (5.1 km/h; 3.2 mph; 4.7 ft/s). [ 1 ] [ 2 ] [ 3 ] Individuals may find slower or faster speeds uncomfortable. Horses have also demonstrated normal, narrow distributions of preferred walking speed within a given gait , which suggests that the process of speed selection may follow similar ...
When each equatorial degree was divided into 18 leagues, the geographical mile was equal to 1 / 54 degree or about 2.06 kilometres (1.28 mi); when divided into 20 leagues, the geographical mile was equal to 1 / 60 degree, approximating the values provided above; and when divided into 25 leagues, the geographical mile was equal ...
Start with fewer miles and then increase over time to create a more sustainable routine. Aim for: anywhere between 2,000 and 8,000 steps per day—which is between one and four miles.
