How long will it take to travel 800000 km?

Answer 1

That depends on the mode of transportation. Walking? Forever and a day.

Driving? A perfectly ordinary automobile can travel at 100 km per hour (60 MPH). At that rate, it would take 8,000 hours.

Flying? An average jet airliner travels a bit over 1,000 km/hour, so you'd log 800 flight hours to reach that total. (For the record, I have about 6,000 flight hours in my logbook, but it isn't ALL in jets; still, I've probably traveled over 800,000 km in my aviation career.)

The Space Shuttle goes about 30,000 km/hour, so under 3 days of orbiting would reach that total. And the Moon is about 400,000 km from the Earth, and the Apollo astronauts traveled there and back in about a week.
