Light travels approximately 186,282 miles per second, so it takes about 1/186,282 seconds to travel 1 mile.
8 minutes
Light will travel 1 miles in about 5.368 microseconds (That means that light will travel about 65,000 miles in the time it takes the average person to blink!)
A lightyear is not a measure of time but a measure of length that light can travel in 1 year. It would take 28 years for light to travel a lightyear
2 days
It takes 1.3 to 1.4 nanoseconds for light to travel 1 foot.
The Earth is 500 light-seconds from the Sun. One second is 10^9 nanoseconds.
It takes approximately 0.13 seconds to travel from England to America at the speed of light, which is about 186,282 miles per second. However, it is currently not possible for any object with mass to travel at the speed of light according to the theory of relativity.
Light travels at a speed of approximately 299,792 kilometers per second in a vacuum. To travel 100 meters, it would take light approximately 0.000000336 seconds.
(Assuming the you are planning on going the speed of light)3,153,600,000,000,000,000,000or3.1 sextillionor3.1 thousand trillionI assume however that you thought this number would be lower. As fast as light is, it will still take around 100, 000 years to cross the galaxy. In one nanosecond light will travel around 1 foot.
Light in a vacuum travels at 300,000 km per second. It will take distance divided by speed time to travel. Or 30 million thousand km divided by 300 thousand km/s = 100 000 seconds. This is 27.8 hours.
It would take (10 divided by 30,000,000,000) seconds to travel 10 cms, which is 0.000000000333333 of a second (approximately!) In nanoseconds this is 1/3rd of a nanosecond. For all practical purposes, for such a small distance, one could consider that the beam of light (in space) would travel that distance almost in an instant. It's that fast!
I make the distance from Perth to Brisbane to be about 3,613.9 kilometers (2,246 miles).The speed of light is 299,792,458 meters per second.At that speed, the trip takes (3,613,900 / 299,792,458) = 0.012 second(12,054,672 nanoseconds . . . 12,054 microseconds)
About 500 seconds
How many hours does it take to get to 4.5 billion km
It will take 1 year, as soon as you and Albert work out how to travel at the speed of light. ;)
Light travels at a speed of 186,282 miles per second. To convert light-years to hours, divide the distance in light-years by the speed of light. Therefore, 310 light-years would take approximately 1,874,579 hours to travel.
