I've heard "one nano for one foot" but never checked it out. Let's do that now: 1 mile = 5,280 feet Speed of light = 186,282 miles per second = (186,282 x 5,280) = 983,568,960 feet per second. One nanosecond = 1 x 10-9 second. Speed of light = 0.9835+ feet per nanosecond You asked for the reciprocal = 1.0167 ns per foot (rounded) It looks like "one nano for one foot" is a pretty good approximation ! If given speed of light in terms of meters first: 299,732,458 m/s (100cm/1m)(1"/2.54cm)(1'/12")(10^-9) > we get (after canceling units) .983374206 1'/s >we need the answer in s not 1/s so we take the reciprocal: (.983374206 1'/s) -1 >we have now satisfied the problem with a solution of 1.01690688 ns/1' My answer is not rounded because of significant digits The units in the conversion above were exact so we should use the 9 significant digits we started with. (please correct if needed)

How many nanoseconds does it take light to travel 3.50?
Light travels at approximately 299,792 kilometers per second in a vacuum. To find out how many nanoseconds it takes light to travel 3.50 meters, we can use the formula: time = distance / speed. Converting 3.50 meters to kilometers gives 0.0035 kilometers, and then calculating the time gives about 11.6 nanoseconds. Thus, it takes light approximately 11.6 nanoseconds to travel 3.50 meters.
How many nanoseconds does it take light to travel 1 foot?
It takes 1.3 to 1.4 nanoseconds for light to travel 1 foot.
How many nanoseconds does it take for light to travel 372 miles?
Light travels at approximately 299,792 kilometers per second, which is about 186,282 miles per second. To find the time it takes for light to travel 372 miles, you can use the formula: time = distance/speed. This calculation shows that it takes roughly 2 milliseconds (or 2,000,000 nanoseconds) for light to cover that distance.
How many nanoseconds does it take to travel 1.9km at the speed of light?
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.
How many nanoseconds dose it take for the light from the sun to reach the earth?
The Earth is 500 light-seconds from the Sun. One second is 10^9 nanoseconds.

473,099,999,999,999,936 nanoseconds.
How many miles does light travel in 1 microsecond in a vacuum the speed of light in a vacuum is 186000 miles per second?
Since a microsecond is a millionth of a second, just divide the distance light travels in one second, by a million.
