The speed of light is 3*10^5 kilometers per second. If a light-year is the distance light travels in one Earth year, how many kilometers are in one light-year? (one earth year=365.25)

9.46 X 10^12 kilometers

Step-by-step explanation:

We will solve this problem by applying s=vt formula.

Here, s = distance

v = 3X10^5 km/s

t = 365.25 days = 365.25 X 3600 X 24 = 31557600 seconds

Now, s = 3X10^5 km/s X 31557600 seconds = 9.46 X 10^12 kilometers
