-- The distance that light travels in some amount of time is expressed in units of distance.
-- The time that it takes light to cover some amount of distance is expressed in units of time.
-- The speed of light is expressed in units of speed . . . distance/time
Not really. A light year is a measure of distance. It is the distance light can travel in one earth year, about 6 trillion miles
False the light year is not a unit of time it is a unit of distance true.
Distance (metres) = velocity (metres / sec) * time (seconds) > velocity of light = 299 792 458 metres per second 1 year = 365.2425 days = 31 556 952 seconds > Distance = 9 460 536 207 068 020 metres Distance = 9.46054 * 1015 metres approx.
The sun is too close to us to be measured in light years; it is 8 light-minutes away.
A light-year is a unit of distance, not a unit of time.

Stars are not measured in light years. The distance between them is.
Distance
Distance
Because that's how it is defined. A light-year is the distance that light travels in a year.
No. A light year is a measure of distance. It is the distance light travels in a year.
'Light-year' is a unit of a distance. It is the distance for light to travel one year. So it is a great distance.
False the light year is not a unit of time it is a unit of distance true.

Speed is measured by calculating the distance you have gone and how long it took you to get there. speed = distance over time
