AnswerClick to flip back
A
1.28 seconds
💡 Explanation:
Light takes approximately 1.28 seconds to travel from the Moon to Earth. The average Earth-Moon distance is about 384,400 km, and light travels at about 300,000 km/s. Calculating: 384,400 ÷ 300,000 ≈ 1.28 seconds. The other options are incorrect - 8.1 minutes is the time for light from the Sun, 3.2 seconds is too short, and 2.3 minutes is too long.
