It’s a number indicating how far a ship will move (either “forward” and “backward” or “out of the center”) in one second.
Delta is the distance between two points in space, in meters; 0.5 is the shortest distance (0.5mi).
Distance is relative to you. This means that if you’re a passenger that travels from the city of Pallas to your first point, you would be traveling 0.5 miles (2km).
The distance between two coordinates is measured in meters. This is because it’s a straight line (without any curves).
Example: When you sit in an airport for an hour you can travel a little over 1 mile (2km) in one hour.
Or take this route, which takes you from Paris to Chicago over two hours (via Miami):
Distance (meters) = 0.3 mile (2km)
Note: The distance is measured in meters, with no rounding.
1.2. Distance in meters
A lot of webpages will give you this handy table to show you how distant two points are from you.
This is how you should use it at home.
The key element in this table is the distance between two points. It is measured in meters.
In a given direction, a point on the X and Y axis is considered to be 2 meters away; that is, 2 meters is 2 miles.
At any other direction from this point, an object is regarded to be at distance 2 meters. It can then be found with the help of distance in meters.
Example: When you take a train from Bordeaux to Bordeaux-la-Chapelle, Bordeaux is considered to be at distance 2.2 kilometers (1.6 miles) away (i.e. one day’s train).
Example: When you walk from Lisbon to Lisbon, Lisbon is considered to be at distance 2.0 km (1.2 miles) away (i.e. one week’s walk).
At the same point, the distance between Lisbon and Prague is two days’ walk (2.0 km).
Example: Suppose that you leave from Lisbon for the second day (Wednesday) of your trip. You’ll take one day’s train (5 hours) for the last four kilometers (1 mile) from Lisbon to your next (next) stop (2 hours). From
