As height is in meter, the distance must be in KM. Therefore 42.226 is correct.

B is correct.
D = 3.855 √(120).
= 42.226.
D = 3.855 √(120).
= 42.226.

Combine correction, height = 0.0673d^2.
Square root (120/0.0673) = d.
d = 42.226 km or 42226 m.
Square root (120/0.0673) = d.
d = 42.226 km or 42226 m.
