If you stand by the sea on a beach, how far away in miles is the horizon?

Answer 1

* Standing on the ground with h = 1.70 m (eye-level height), the horizon is at a distance of 4.7 km [2.92 miles]
* Standing on a hill or tower of 100 m height, the horizon is at a distance of 36 km. [22.37 miles]

Answer 2

Take the square root of your height above the surface of the water and then multiply that by 1.17 to get the distance to the horizon. For instance, if you're standing right at the shore and your eye level is 5 feet above the ground, then the distance to the horizon would be the square root of 5, which is about 2.24 then multiplied by 1.17 is 2.62 miles. The distance to the horizon increases with increasing height due to the curvature of the Earth.

Answer 3

Why do human beings provide crap solutions. there's a neat formulation, in case you're attentive to metric (probable mark downs all human beings): Multiply the sq. root of the top in meters above sea point via 3.sixty seven, and the respond is in kilometers eg in case you're on the water's ingredient and your eyes are a million meter above the sea point (sitting in sea coast chair), the horizon is barely 3.sixty seven kilometers away. in case you're on a extreme sand dune, 10 meters above sea point, the horizon is 3.sixty seven x 3.a million kms away approx in case you're on a extreme cliff at one hundred meters, the horizon is 36.7 kms away (3.sixty seven x 10) it would be obtrusive that the better you're, the greater you spot over the curve of the Earth. ______________________________________..... Yeh, David D is going into extreme college math. Who desires it – see my trouble-free formulation. additionally, what's it with human beings and their worry of the simplicity of metric? look at his 22514 ft it particularly is 4,264 miles (possibly having to divide via a daft 5280). Now look on the metric equivalent – 6861 meters = 6.861 kilometers. Hmmm – get with the plan you adult males. The Olympics are arising quickly, and you will see that each and every distance, top, shot putt, weight bring up, etc is carried out in metric. and that they've been doing that through fact the outset in 1896. I betya there are nevertheless colleges interior the States the place they run the hundred yards (one backyard = 3 ft = 36 inches, = a million/1760th of a mile LOL). i'm consistently greatly surprised the human beings have a decimal forex. in line with probability if that they had had the previous Brit forex like I had to benefit in school (a million pound = 20 shillings, a million shilling = 12 pennies), and had to objective and do multiplications and divisions with that nonsense, they could have a some distance fit admire for the utter simplicity of the metric equipment. ______________________________________..... and that i'm greatly surprised at Haug – what does sea point recommend? At sea point you're interior the water with your eyes merely above the waves – how some distance could you spot from there?. It makes an limitless diverse each and every meter you're greater than sea point. So, in case you're status on the sea coast, you will see the horizon plenty added away than somebody sitting on the sea coast. And this guy is a suited contributor???????

Answer 4

There is a simple formula for the line of sight
Distance= 1.25 x the square root of the height of the observer in feet. The distance is given in Nautical miles.
Example: A6.2 feet tall person (The eyes 6 feet from the water level will see the Horizon at 3.06 miles.
Square root of 6=2.45x1.25=3.06

Answer 5

With the help of dear old Pythagoras, it worked out like this:

Distance to horizon = Square root of (h^2 + 2rh)
Where units are Km and
r=6366 (radius of Earth)
h = Your eye height above sea level

So if your eyes are 1.5m above sea level
h=1.5/1000

For
h=1.5m Dist = 4.4 Km
h=5m Dist = 8 Km
h=10m Dist = 11.3Km
h=20m Dist = 16 Km
h=30m Dist = 19.5 Km

Sorry, I worked it out in Km, 1 Mile is about 1.6Km.

Answer 6

At sea level a 6 foot tall person can see for approximately three miles.

Answer 7

10 miles

Answer 8

15 ish miles

Answer 9

If you are standing up, it is about 25 miles.

Answer 10

It is as far as the eye can see, so it depends on your eyesight.
If you are near-sighted it will seem a lot nearer than if you are far-sighted.
