what is the difference between nautical miles and road miles?

A nautical mile measures distance and a knot measures speed. A nautical mile is based on the circumference of the earth, and is equal to one minute of latitude. It is slightly more than a statute (land measured) mile (1 nautical mile = 1.1508 statute miles ). Nautical miles are used for charting and navigating.

Generally, “far away” is more “a place that is a long way away” and “far” is just “a long distance”. Also, in casual speech, “far” without “away” is (in its spatial sense) more often found in questions or as “not far” than “far”; words like “long way” are more often used for the positive senses.

The distance between degrees of longitude is about 60 nautical miles at the equator. It is less further north or south as the longitude lines converge towards the poles. Degrees of latitude are always 60 nautical miles apart. At the equator, a grid of 1° of longitude by 1° of latitude covers about 3,600 square miles.

Within an area that borders an ocean, you are either on the coast or you are inland, ie, not on the coast. If you are on the coast, you can see ships. If you are further inland, you cannot. Overseas means “across the sea” (or ocean).

The distance difference in the longitude direction is EarthRadius * longitude difference * cos(latitude) . We multiply by cos(lat) because the longitude degrees don't make the same km distance if the latitude changes.

The main difference that separates a car GPS from a truck GPS is the ability to determine whether a route is suitable or not. While the default map provided by a normal GPS is the same in principle, the whole difference lies in the ability of discerning extra data from the map, which a truck GPS does.

(a) Distance travelled is the actual length of the indirect path covered by the body whereas displacement refers to the straight line path between the initial and final positions. For e.g. In the figure given below, a body moves from point A to point B and then from point B to point C.

A Nautical mile is based on the circumference of the earth, and is equal to one minute of latitude (1/60th of a degree). It is slightly more than a statute mile (1 nautical mile = 1.1508 statute miles.)

Departure is the distance along a parallel between two points. Whereas a degree of latitude is always the same distance, a degree of longitude is different in length at different latitudes. In practice, this distance is usually given in nautical miles.

With the exception of military and scientific usage, the United States does not use the metric system, instead retaining its own customary units. This means that road distances are indicated in miles, and speed limits are indicated in miles per hour (mph).

As nouns the difference between distance and range is that distance is (countable) the amount of space between two points, usually geographical points, usually (but not necessarily) measured along a straight line while range is a line or series of mountains, buildings, etc.

As nouns the difference between distance and interval is that distance is (countable) the amount of space between two points, usually geographical points, usually (but not necessarily) measured along a straight line while interval is a distance in space.

A nautical mile is 10 cable lengths, or 6,076 feet. A knot is the measure of speed on water. One knot is 1 nautical mile per hour.

In very broad terms: Inshore fishing is closer to the coast, while offshore coast is farther away from the coast. Depending on where you're fishing determines exactly where that line is. For the Gulf of Mexico, the line is generally 9 miles from the coast.

– The main difference between a highway and an interstate is access. Unlike highways which are controlled-access or limited access roadways, interstates are restricted access roadways that go across state boundaries to connect different states.

In very broad terms: Inshore fishing is closer to the coast, while offshore coast is farther away from the coast. ... Others say that offshore fishing is “when you can't see land.” For what it's worth, NOAA (National Oceanic and Atmospheric Administration) considers offshore at 20 miles from the coast.
