Answer:
Light travels at approximately 186,282 miles per second (299,792 km per second). Therefore, a light shining from the surface of Mars would take the following amount of time to reach Earth (or vice versa): Closest possible approach: 182 seconds, or 3.03 minutes. Closest recorded approach: 187 seconds, or 3.11 minutes.
Explanation:
km light years
54,600,000 5.7712 x 10-6
54,700,000 5.7818 x 10-6
54,800,000 5.7924 x 10-6
54,900,000 5.8029 x 10-6
So 54,600,000 km is equal to 5.7712245538e-6 light years.
Hope this helps have a wonderful day!!
