However, welcome news regarding Scottâs future came early in 1919 with the War Departmentâs decision to purchase Scott Field. Scottâs central location and the exceptional price of $119,285.84 influenced this decision and set the stage for Scott Air Force Baseâs amazing military future. In 1920, the government decided that the field should be turned over to the lighter-than-air branch of the Air Corps.
40075.02 / 360 / 60 = 1.8553 km. One minute of longitude on equator is 1.8553 km. Please note - on equator (i.e. on 0 degree of latitude)! Because the length of parallels decrease toward the north or south pole, the length (in km or miles) of minute of longitude differs for different latitudes.
Longitude at a point may be determined by calculating the time difference between that at its location and Coordinated Universal Time (UTC). Since there are 24 hours in a day and 360 degrees in a circle, the sun moves across the sky at a rate of 15 degrees per hour (360Â°/24 hours = 15Â° per hour). So if the time zone a person is in is three hours ahead of UTC then that person is near 45Â° longitude (3 hours Ã 15Â° per hour = 45Â°).
