Question 592130: Because of Earth's curvature, a person can see a limited distance to the horizon. The highere the location of a person, the farther that person can see. The distance D in miles to the horizon can be estimated by D(h) = 1.22√h, where h is the height of the person above the ground in feet. How high does a person need to be to see 23 miles?

Because of Earth's curvature, a person can see a limited distance to the horizon.
The higher the location of a person, the farther that person can see.
The distance D in miles to the horizon can be estimated by D(h) = 1.22√h, where h is the height of the person above the ground in feet.
How high does a person need to be to see 23 miles?
:
1.22sqrt%28h%29 = 23
;
sqrt%28h%29 = 23%2F1.22
Square both sides
h = 355.4 ft
