A. Kilometers per minute
B. Kilometers per second
C. How far can light travel in 7 minutes? Kilometers
D. All of the above

Answer 1

Light travels 126,000,000 kilometers in 7 minutes, as it moves at a speed of 18,000,000 kilometers per minute.

Step-by-step explanation:

Light traveling about 180,000,000 kilometers in 10 minutes equates to a speed of 18,000,000 kilometers per minute. To find how far light can travel in 7 minutes, you simply need to perform a proportional calculation using the given rate. Knowing that light's speed is approximately 300,000 kilometers per second, we can construct the following calculation:

• Speed of light = 18,000,000 km/minute
• Distance in 7 minutes = 18,000,000 km/minute x 7 minutes

Thus, light can travel 126,000,000 kilometers in 7 minutes. So, the correct answer to the question about how far light can travel in 7 minutes would be option C. Kilometers.
