Use a chart not a map. WGS 84 is probably the best datum
The captain asked me "how many nautical miles are we off the shore?"
Over 250 miles
A giraffe can sprint thirty five miles per hour over short distances. They can run comfortably at ten miles per hour over longer distances.
Nautical miles are used as a distance measurement both in the air and on the sea, but not so often on the ground. So if "air miles" refers to the statute miles that we use over land, then a nautical mile is about 15% longer. Therefore, to convert one to the other, multiply by 1.15. 1 nm = 1.15 miles 100 nm = 115 miles 20 nm = 23 miles and so on.
A distance of around 5,700 miles to over 7,900 milesseparates Russia and Suriname. The distance from St. Petersburg in western Russia to Suriname is 5,718 miles [9,202 kilometers; 4,969 nautical miles]. The distance from Novosibirsk in southwestern Russia is 7,600 miles [12,231 kilometers; 6,604 nautical miles]. The distance from the Kamchatka Peninsula in far eastern Russia is 7,920 miles [12,746 kilometers; 6,882 nautical miles].

About 5000 miles or more or less
Measuring the path using Google Earth, by sea from London to Sydney using the Suez Canal was around 12,000 nautical miles. Using the Panama Canal was closer to 12,500 nautical miles using a similar method to draw the path on Google Earth.This doesn't take into consideration the curvature of the Earth and both were as close as I could get to a direct sea route. Using http://www.freemaptools.com/measure-distance.htm the direct or 'as the crow flies' route is a shade over 9,200 nautical miles.
Over 3,000 miles away from London, England, is Freetown, Sierra Leone, at a distance of 3,056 miles. That equals 4,918 kilometers or 2,656 nautical miles.
The distance between the above two places is nearly 986 miles. This is approximately equal to 1587 kilometers. These distances are point to point straight distances. The actual distances may vary according to the flight path chosen.
That cannot be calculated without knowing the average speed over that distance.
Just a bit over 500 nautical miles.
