12000 lunar orbits is a distance, not a speed, therefore it's not the speed of light.
That will completely depend on where the Earth and the comet are in their respective orbits. No single answer is possible.
You must calculate using the speed of gravity as instantaneous otherwise a balanced moving mass system is no longer balanced and is out of alignment.
Yes. Comets have highly elliptical orbits. They move fastest when they are nearest the sun and slowest when they are farthest away.
The speed of sound has nothing to do with the height above sealevel. It has only to do with the temperature there. The higher - the colder.
speed of light I think well it sounds right:)
Roughly 308 minuites (this will vary depending on where Earth and Pluto are in their orbits).
Nobody made it up, the speed of light is an inherent property of spacetime and the electromagnetic force. It was first observed and measured during observations of the orbits of the moons of Jupiter.
That will completely depend on where the Earth and the comet are in their respective orbits. No single answer is possible.
What is weight of 5000 Liter High speed diesel
23 mph

That depends on the speed at which one is traveling.
Mercury
The Earth
The Earth
That depends on the average speed. Choose an appropriate speed, then divide the distance by the speed.
Yes. Comets have highly elliptical orbits. They move fastest when they are nearest the sun and slowest when they are farthest away.
