Since no observer CAN go at the speed of light, this question is the equivalent of asking, "If two plus two were to equal five, can you make money by exchanging four one-dollar bills for one five-dollar bill?"
The simple facts are that (1) two plus two does NOT equal five and (2) no observer can travel at the speed of light.
if you are going the speed of light, it would take 1 year.
At a speed 212 000 kilometers per second you have a relativistic gamma of 1.41, and you will time 365 days of travel when travelling one light-year. You would think that effectively you were going at light-speed! An observer would see you going slower though, and would time your trip to over 516 days.
No human or machine can travel the light of speed. No matter how close you are to the speed of light if you have all the thrust in the universe you cannot get going past the speed of light. The familiar notions of absolute space and absolute time independent of your relative motion must give way.
The formula to calculate travel time at the speed of light is distance divided by the speed of light. The nearest star to Earth is Proxima Centauri, which is about 4.24 light-years away. Therefore, the travel time to Proxima Centauri at the speed of light would be 4.24 years.
Light travels at a speed of about 186,282 miles per second. The time it takes for light to travel to Jupiter depends on the distance between Earth and Jupiter, which varies as they orbit the sun. On average, light takes about 33 minutes to travel from Earth to Jupiter when they are at their closest approach.
This is an unanswerable question, since time is a dimension and the speed of light a measurement. The two are directly related, however, insofar as approaching the speed of light inversely affects the relative speed with which you travel through time. For instance, one year on a spaceship going 99% the speed of light (it is impossible to reach the speed of light relative to local space-time, in that paradoxical scenario time would stop completely) would cause you to return to an Earth that has aged hundreds or possibly thousands of years (I'm not sure the precise speed to time conversion formula).

distance = speed x time. Multiply the speed of light (in miles/second in this case) by the time in seconds, to get the distance travel in miles.
There hasn't been up to time of answer an aircraft fly at or higher that the speed of light
Light waves always travel at the speed of light in a vacuum, regardless of the observer's frame of reference.
900 billion years - if you travel near the speed of light. If you travel at any slower speed, it will take longer of course. But do some reading on time dilation - if the traveller travels at a speed very near the speed of light, from his point of view it will take much less time.900 billion years - if you travel near the speed of light.

Light always travels at the speed of light. The only time that's 299,792,458 meters per second is when the light is in vacuum.
