Answer:
Explanation: To solve this problem, use the formula for distance = speed x time. The speed of light is 3.0 x 10^8 m/s, and the time it takes for light to reach the earth from the sun is 8.3 minutes. So, distance = 3.0 x 10^8 m/s x 8.3 minutes. Converting 8.3 minutes to seconds, 8.3 minutes = 8.3 x 60 = 498 seconds. So, distance = 3.0 x 10^8 m/s x 498 s. To convert the distance to kilometers, divide the result by 1000. So, distance = 3.0 x 10^8 m/s x 498 s / 1000 = 1.5 x 10^10 km. Therefore, the correct answer is b) 1.5 x 10^10 km.
