MN is the diameter of the planet which is
AM and NC are the distance of moons from the surface of the planet.
Since, angle ABC is given as 90 degree, it means, line AC will pass from the diameter of the planet.
So, distance between moon A and moon C is =
Hence the distance between point A and point C is 300000 Km. : Answer
