the maximum viewing distance on a clear day is related to how high you are above the surface of the earth. this relationship can be approximated by the formula h=0.075d^2, where d is the max distance, in kilometers, and h is your height, in meters, above the ground.
how high do you need to be in order to see a distance of 25km?
just plug in your numbers
h = 0.075 * 25^2
To find the height (h) required to see a distance of 25 km, we can use the given formula h = 0.075d^2.
Substituting the value of d as 25 km into the formula, we have:
h = 0.075(25)^2
= 0.075(625)
= 46.875 meters
Therefore, you would need to be approximately 46.875 meters above the ground to see a distance of 25 km on a clear day.
To find the height needed to see a distance of 25 km, we can rearrange the formula h = 0.075d^2 and substitute in the given distance, d = 25 km.
h = 0.075 * (25^2)
= 0.075 * 625
= 46.875 meters
Therefore, you need to be at a height of approximately 46.875 meters above the ground to see a distance of 25 km.
