What is the distance to the earth’s horizon from point p?

156.7 miles.

Step-by-step explanation:

The radius and the tangent at the point of contact form a right angle so we can apply the Pythagoras theorem:

( 3959 + 3.1)^2 = x^2 + 3959^2

x^2 =  3962.1^2 - 3959^2

x^2 =  24555.41

x =  156.7 miles.
