The distance from the Earth to the moon is about 384,000 Kilometers or 238,606 Miles, so it would be about 170 hours or 7 days.
So if you're going at 1400 miles per hour, that means you can do 1400 miles in an hour. That means you have to divide 42 miles by 1400 miles per hour. You will get a 0.03 Hours, which you could multiply by 60 to get the amount of minutes. This is then equal to 1.8 minutes or 1 minute and 48 seconds.
20 hours
In an hour, you would travel 17500 miles. At that speed it would take about 13 hours and 39 minutes to reach the Moon and about 221 days to reach the Sun.
Approximately three weeks at 500 miles per hour.
Usain Bolt can reach up to 23.35 miles per hour
1 hour
It would take 4,620,000,000.
Using 238,900 miles as the distance to the moon the trip would take you about five months at 65 miles per hour. Now, imagine trying to reach the sun at 65 mph; the trip would take about 163 years.
1.1 miles per hour.
If that's really what the question is, the answer is 1400 mph. If the question is actually "A truck travels 1400 miles in 20 hours, what is its average speed?" then the answer is 70 mph.
The trip would only take 5.64 seconds to reach Pluto (about 4.7 billion miles) at that speed.
Four hours.
