"Light-year" is not a speed, it is a distance - the distance light travels in a year.
The speed of light is 300,000 kilometers per second. If you multiply that by 3600 (seconds/hour), you get the speed in km/hour.
Well... yes, but it's not a very useful one. Light travels one light year in... one year. So the speed of light (which you cannot accelerate to) is about 1/8766 light years per hour.
Let 'K' be the speed expressed in kilometers per hour.(1K kilometers/hour) x (1 light-year / 9.46073 x 1012 kilometer) x (1 hour / 60 minute) =( 1.76167 x 10-15 K ) light-years per minute (rounded)
kilometer, AU (astronomical unit), light year, parsec.
The average top speed of a car is 120 to 150 miles per hour in the year 2008. it can go to 200~300 MPH.
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.
A light year is the distance that light will travel in a vacuum in a year. Nothing can travel that distance in an hour so a lightyear per hour is a meaningless concept of speed. Though impossible to attain, it is a measure of speed while a kilometre is a measure of distance. There is no direct relationship between the two.
1 light hour like how a light year is how far light travels in a year.
We don't know what "hour second" means, and have a nagging suspicion that it's quite meaningless. In vacuum, the speed of light is roughly -- 186,282 miles per second -- 670,615,200 miles per hour -- 16,094,764,800 miles per day -- 112,663,353,600 miles per week -- 5,878,715,206,000 miles per year.
It is known as a light year.
One Light Year at Snail Speed was created in 2003.
The speed of light is 299,792,485 meters per second so if you travelled at this speed for a whole year that would be a light year.
A light Year is longer. a light year is the distance light travels in one year. it is often used do describe the distance of objects in space because they are very far away and light travels very fast so a light year is very far.
