Sagot :
Here's a hint : A light year is a distance, not a time.
A light year is a unit of length used informally to express astronomical distances.
A light year is a unit of length used informally to express astronomical distances.
A light year is the distance light travels in one year.
Let's figure out what this distance is shall we...?
We know that speed = distance / time, therefore distance = speed x time.
Speed of light = 299,792,458 m/s
Time (One year) = 31,536,000 s
That is a ridiculous:
9.454254955 x 10¹⁵ metres,
Which is approximately:
9,400 trillion metres.
Only "one light year" away... That's a hell of a distance.
