Question

The equation,

 
 D=sqrt(1.30h), can be used to approximate the distance, D, in nautical miles that a person can see to the horizon from a height, h, in feet. This equation includes a correction for the refraction of light. Suppose that you are in an airplane. By choosing any height, find the corresponding distance that you should be able to see to the horizon. Include the height and the calculations needed to find the distance. Include units with your answer, and show all work for full credit.

Basically, the problem says that you can pick any number to plug in for the formula. So, 

Equation:    D=sqrt(1.30h)

For example, you can choose the height of , let's say, 1250 ft. 

Let`s plug that in the equation.

D = sqrt(1.30 * 1250)
D= sprt (1625)

So, i used the height of 1250 ft. 
I`m not too sure about the sqrt. What do they represent? 
Hope you get it. I got this far (:

if H is in feet then D will be in nautical miles (1852 meters).

So if you're in a plane 300 feet up it would be

D= sqrt (1.3 * 300)
D = sqrt (390)
D is approximately 19.749 nautical miles or 

or about 722,322.6 meters

sorry that my previous answer was wrong.  It's late and I missed something when reading the first time through.

if you cant solve this then you need to retake the class. It will be better for your future. what is so confusing about it? Choose ANY height!

Is your calculator broken?  This is a plug and chug problem.
