384 000/2.4 = 320 000 km/s.

Speed of light is 300 000.

But long waves travel quicker in glass. Would be the same in space?

No. Maybe I don't understand the complex calculation under your quoted
division by 2.4, but....

Your "mean distance" have to be doubled: received *back* in 2,4 sec mean
that the signal traveled the double distance.
At minimum distance the moon is 356375 km far from earth. 356375*2 is 712750
km, that at light speed means a travel time of 2,37 sec.

Any greatest distance agree with classical physics laws, and a normal mind
don't care if the light travel faster, maybe care about the distance of the
moon at the time of test: exactly 360000 km from the earth.

Don't you ?
