Best Answer: It depends on your height above the surface of the water. where h is the height above ground or sea level (in meters) of the eye of the observer. For an observer standing at sea level with h = 1.70 metres (5 ft 7 in) (average eye-level height), the horizon is at a distance of 4.7 kilometres (2.9 mi).
Best Answer: The horizon distance as seen from an elevated position can be calculated by: Dist to horizon = Sq root of, ((radius of earth + hight above ground)^2 - radius of earth^2) http://www.boatsafe.com/tools/horizon.ht... says if you are on Mt Everest, 29006 feet high, unobstructed horizon is at 229 miles. So your figure of 800 miles is a bit high, by about 4 to 10 times. But if this girl's city is quite high also, and the planet this is on is much larger than the Earth (curve of horizon is larger) then 800 miles might be possible.
