If you were at sea and there was a ship on the horizon, how far are you from it ?

well um, there would have to be more info to solve this. if it is directly horizontal from you, then the ship could be infinite distance from you (or as far as u can see).

Hmmmm.  May I know where you're at, Sir?

would you be able to find a drop of tea in the ocean?\nthe answer is with no dought no so that means she will never forget you........

Pacific, by a wide margain.\n\nPacific Ocean Coastline: 7,623 miles\nAtlantic Ocean Coastline: 2,069 miles

100 feet  -- 30.48 miles to horizon\n3000 feet -- 58 miles to horizon\n\nd = sqr(2*r*h)

This sounds like a nautical question indeed!\nHmmmmm...

It depends a lot on how high above the water your eyes are and how tall the distant object is.\n\nThe radius of the Earth at the equator is 6378135 meters.  Assume your eyes are 2 meters above sea-level, and the distant object is at sea-level.\n\nYou have a right triangle, where the longer leg is the radius of the Earth, and the hypotenuse is 6378315 + 2.  The shorter leg is the distance to the horizon.\n\nThe distance to the horizon = √(6378317^2 - 6378315^2) = 5051 meters, or about 3 miles.\n\n\nIf the distant object is 2 meters above sea-level, then it'll disappear when it's another 3 miles past the horizon, or 6 miles from you.

Off the shore is offshore.  If you are leaving the US and trying to get into international waters, the distance is 2 miles.

S=1.317h 1/2  S is the distance from to the horizon, h is how much above sea level. The AMS states that the horizon is at minimum 3 miles away.   So for a person whose eye level is 5 ft above sea level, the horizon is 1.317m(5ft)(1/2) which equals 3.29 miles

The Sea. The sea can make a ship float but not a pin.

Give us a hint, what continent are you on?

Get in touch with me, buong, I am, and I will be leaving in 4 days. My name here is Glalien, I come from Pleedeeze, it takes 8 hours to arrive here from our planet, via time warping. Our ships are made of nothing you have on this planet. Our propulsion is of magnetics. You will not believe me if I tell you why we are here. Look me up.

You would be at 40 46.12'S, 106 41.52'E which is in the Indian ocean. The closest land mass is 700 Miles North East (Western Australia).  \n\nThere is almost Nothing near this location but water. \nPerhaps an uncharted Island?\n\nCheck it out with google earth.\n\nYou can use the measure tool to find the point where the straight line will ROTATE like a spinning compass because the line always shows the shortest distance.\n\nAs the crow flys (or swims in this example), these two points are 12,414.94 Miles Apart.

I assume you mean how far away is the horizon, which isn't quite what the wording of your question really asks.\n\nAnyway, it is a simple geometry question. Construct a triangle. One point is the center of the Earth, one point is at your eye and one point is at your horizon. The horizon is that place where your line of sight is tangent to the curved surface of the earth, which means that the angle between the line from your eye to the horizon and the line from the center of the Earth to the same point on the horizon is 90 degrees. So you have a right triangle. The hypotenuse is the line from your eye to the center of the Earth and it's length is the radius of the Earth plus your height. That length, squared, is the sum of the squares of the other two sides. One of those sides is the radius of the Earth and the other is the unknown distance to the horizon you are trying to find. Just do the algebra to solve for the third side, which is the distance to the horizon. I think it is about 20 kilometers for the average person.

good question. depends on how far away it is. if the horizon is flat and you can see 10 miles away then it would be like a circle with a 20 mile radius...becuase it goes all the way around you...get it?
