The distance from a planet to its sun is approximately 110 million kilometers. If the speed of light is 3.0 x 10^5 km/sec, how long does it take light from the sun to reach the planet? If a solar flare occurs right now, how long would it take before it would be visible on the planet?

Round your answer to the nearest second.

It takes  seconds for the light from the sun to reach the planet.

The solar flare would be visible in 

 seconds.

Thank you for the opportunity to help you with your question!

Time taken by light from the sun to reach the planet = distance / speed of light

                                                                                     = 110 million kilometers / 3 x 10^5 km/sec     

                                                                                     = 366.66667 s = 366.7 seconds

The solar flare would be visible in ,

                                                  = 2 * 366.7 = 733.3 seconds
