How long would it take to get to mars if traveling at a speed of 100000 kmhr?
The closest that earth and Mars can ever get is about 78.3 million km.Spacecraft never travel in straight lines. But just to get an idea, let's say you could make the tripon a straight-line route.At 100,000 km/hr, you'd pass the moon in a little under 4 hours (that much took the Apollo astronauts 3 days),and the whole trip to Mars would take 783 hours, or 32.6 days.
