1 light year = 31,556,926 light seconds.
None. Seconds are a measurement of time and a light year is a measurement of distance.
1 light year = 5.10827668 × 1012 knots There are 60 Seconds in a Knot, so there are 3.06496601 × 1014 Seconds in a light year.
There are only 31,536,000 seconds in a year. So, light can only travel for 31,536,000 in a year.
light travels at 175000 miles per second divide 500million by 175000 and you will see how many seconds it takes a light year is 175000x seconds in a year try it
The moon is about 1.27 light-seconds from earth, or 0.0000000405 light-year.
None, since a light year is a measure of distance and not of time.
The distance from the earth to the sun averages 499 light-seconds,or 0.0000158 light-year.
A light year is a distance, not a time.
About 1.5 light-seconds to the Moon.
Having "A light-year is the distance light (speed = 2.998 108 m/s) travels in one year," you will then find how many seconds are in a year (31,556,926 seconds), multiply that number by 19 (given). Once you get how many seconds total in 19 years (599,581,594 seconds in 19 years) you will then multiple that number times the speed (2.998 108 m/s).Final Answer: 1.798 x 10172med
The moon is about 1.5 light seconds away from the earth
Multiply speed of light per second by seconds in a year
