Example 2. If the light from the Sun
reaches us in 8.3 light minutes, how far is the
Sun from the Earth?
In this question the light minute is time but in general the distance traveled by light in a minute is known as a light minute.
So when should we know when it's saying time or distance traveled by light??

Answer:Answer and Explanation:
1.And the time taken for a light ray to travel from the sun to the earth is: t=8.3 minutes=8.3×60 s=498 s t = 8.3 m i n u t e s = 8.3 × 60 s = 498 s . This is the distance between the earth and the sun.
2.The time light takes to reach us from the Sun is about 8.3 minutes. Note that the speed of light is in units of km/ sec so we will have to convert minutes into seconds. 8.3 minutes = 498 seconds
