The speed of light is 299,792,458 m/s. distance/speed=time. time=100 years. which is 3153600000 seconds. 4 light years is 299792458*316536000=9454254955488000 meters. So, 9454254955488000/x=3153600000. 9454254955488000/3153600000=2997924.6 m/s. That's 10,792,528.488 km/h. Just to put that in perspective, the fastest speed humans have achieved is about 250,000 km/h (Helios 2 spacecraft.)

How long to travel to Andromeda galaxy?
Traveling at the speed of light, it would take about 2.5 million years to reach the Andromeda galaxy, which is approximately 2.537 million light-years away from Earth. However, current technology is far from achieving such speeds, making intergalactic travel to Andromeda currently impossible for humans.
How fast does light travel from the sun to the moon?
Light takes about 1.28 seconds to travel from the Sun to the Moon. This speed is approximately 299,792 kilometers per second, which is the speed of light in a vacuum.
How long would it take to go one light year?
Depends on your speed. A light year is the distance light travels in a year. If you traveled slower it would take longer.Depends on the speed you are going.At the speed of light one year.See related question for details of a light yearJust like any other distance, it depends on the speed of travel.-- At the speed of light, radio, x-rays, etc., it takes 1 year.-- At 1 million miles per hour, it takes about 671 years.-- At 60 miles per hour, it takes about 11.2 million years.A light year is the distance that light will travel in one year in a vacuum. The speed of light is 186,000 miles per second. So, light will travel about 5.8 trillion miles in one year. Now, to answer the question. The answer depends on how fast you are traveling. If you were in a space ship travelling 99.9999% the speed of light, it would take you about a year to travel a light year. Now, there is currently no human-made space craft, that we know of, that can travel that fast. The space shuttle travels at about 17,500 miles per hour. In order for the space shuttle to travel one light year, it would take about 38,262 years.
How long would it take by spaceship to reach the vega star?
That depends on how fast your spaceship can travel, and what kind of a route you follow.Spacecraft never travel in straight lines. But if you could do that, and if you kicked it up to,let's say, a million miles an hour, then you'd pass the moon in 14 minutes (it took the Apollomissions 3 days), and you'd be at Vega in only 16,970 years !
How much distance does light travel in 1000 light years?
Well, imagine a bright beam of light joyfully hopping through space like a little firefly. In 1000 light years, that sweet light would travel a whopping distance of... 1000 light years! Just like a peaceful painter creating a masterpiece, light spread its glow far and wide in the vast universe.
Which travel faster in coated glass pipe sound or light?
No matter what you do to either of them, light is always going to travel at least several hundred times as fast as sound, and most generally about 800 thousand times as fast as sound. Sound will never travel faster than light, in any situation.
How long would it take to travel 4 000 light years?
Like any distance, it depends on how fast you are going. At the speed of light it would take 4,000 years to travel that distance.

What is 123.23 light years in earth years?
If you are asking how long it would take to travel the distance of 123.23 light years, then that would depend on how fast you are traveling. Because a light year is a measure of distance not time.
How many miles does light travel in a generation if it travels 100000000000000000000000 miles a second?
First of all, light does not travel that fast. Light travels approximately at 299792458m/s. Assuming ~30 years is a generation, then we get 1181781869436000m or 734325209175.91267000715819613457 miles.
