Answer:

About 145 miles.

Explanation:

Assume that the distance from the center of the earth to any point on the earth's surface is 4,000 miles.

Step-by-step explanation:

Answer:

About 145 miles.

Explanation:

Assume that the distance from the center of the earth to any point on the earth's surface is 4,000 miles.  

Step-by-step explanation:

r  =  4000

v  =  13796/5280

(divide by 5280 to convert to miles)

Using Pythagorean's Theorem:

a^2  +  b^2  =  c^2

a^2  +  4000^2  =  (4000  +  13796  /5280)^2

a^2  =  (4000  +  13796   /5280)^2  −  4000^2

a  =  √(4000  +  13796   /5280)^2  −  4000^2  ≈  144.6

This is just a shrunk down version so it is easier to read. All credit goes to the other answer.
