Knowing where you are is only one part of getting to where you're going. -- If you know your own latitude and longitude, AND the latitude and longitude of where you want to go, then you can calculate the DIRECTION you need to sail in order to get there by the shortest route, and exactly how far that is. -- If you only know your own latitude and longitude and nothing else, then perhaps the most useful application of that knowledge takes place when you need to radio the Coast Guard and ask them to come out and rescue you. If you can give them that information, then they don't have to hunt for you when they get to the general area.
You can't sail from London to Cologne.

how long does it take to sail from Pakistan to England
Try looking at a map and you'll see that Johannesburg is about 500 miles from the nearest coast!!
It is called the Prime Meridian, and all nations have agreed that it's the line at zero longitude. That way, if there's a ship sinking, and ships from 35 different countries all want to sail over there and help it, the ship that's in distress can tell all of them the same longitude number, and they'll all wind up at the same place, because they all agree on where the measurement of longitudes begins. Of course, they also need a latitude number. But you get the idea.
