3.1 minutes
....
56x10^6 miles x (1.61km/ 1 mile) = 9.016x10^7 km away is the closet then...
speed of light, 3.00x10^5 km/second....
(1 second/3.00x10^5 km) * (9.016x10^7 km) = 301 seconds....
...301 seconds * 1 minute/ 60 seconds = 5.02 minutes
...I get 5.02 minutes.
=======================================
Marvelous ! Now we have two answers to the question ... The first contributor
said 3.1 minutes, and the second one said 5.02 minutes. Which one is correct ?
They can't both be right.
Or can they !
Take a look at the ratio of the two answers: 5.02/3.1 = 1.61935... Does that number
look familiar at all ? It should. It's within 0.63% of the number of kilometers in 1 mile.
The first contributor looked at the "56 million" in the question, said to himself
"that must be kilometers", and worked the arithmetic that way.
The second contributor looked at the "56 million" in the question, said to himself
"that must be miles", and worked the arithmetic that way.
It's not too often that you get two wildly different answers to the same question
that are both correct, and you get to choose which one you like. But this is one of
those occasions.
The whole problem goes back to the question, where "56 million" is stated without
units ... a big no-no in just about any subject that involves measurements.
Spacecraft have been lost over sloppy work like that.
We'll take your word for it and use the distance of 400 million km.The speed of radio (and light, heat, UV, X-ray, etc.) is 300,000 km/sec.Time = (400 x 106) / (300 x 103) = 1,333 seconds = 22.2 minutes
A spacecraft can travel forever in space because there is no air resistance or friction to slow it down. Once a spacecraft achieves a certain speed, it will continue to travel at that speed unless acted upon by another force, such as gravity or propulsion systems.
If you could cross space directly and ignore Newton's laws like in Star Trek, You would need to cross between 54,710,000 and 401,307,000 kilometers depending on the current orbital/precession status of both planets. However, since current Earth spacecraft burn and coast into an elliptical orbit around the sun such that Mars' gravity will catch the spacecraft; the travel distance to Mars is less than about half of the circumference of Mar's orbit, or about 715 million kilometers, and more than about half of the circumference of the Earth's orbit, or about 470 million kilometers. Differences in designs of spacecraft can change these numbers drastically. Hence it is usually easier to simply refer to the direct line-of-sight distance between the planets.
A person will travel at the same speed as the spacecraft from which they have exited since they are no longer being propelled by any additional force. Their speed would be determined by the velocity of the spacecraft at the moment of exit.
The time it would take to travel 930 million kilometers in space depends on the speed of the spacecraft. For example, if a spacecraft is traveling at the speed of light (299,792 kilometers per second), it would take approximately 3,100 seconds (or about 52 minutes) to cover that distance.

It would take approximately 3 seconds for a radio signal to travel from Earth to a spacecraft that is 900 million meters away. This is because radio waves travel at the speed of light, which is approximately 300 million meters per second.
The word is astronaut. It means a person who is trained to travel in a spacecraft.
It would take 10 seconds.
The time it takes to travel 1 million miles in space depends on the speed of the spacecraft. For example, if a spacecraft travels at 25,000 miles per hour, it would take approximately 40 hours to cover that distance. However, if traveling at the speed of light (about 186,282 miles per second), it would take roughly 5.3 seconds. The actual duration varies significantly based on the technology and mission profile of the spacecraft.
It is the spacecraft voyager 2 , it is the only spacecraft to visit Neptune, and travel further.
