Approximately how long does it take for sunlight reflected from the lunar surface to reach Earth?

The correct option is 1.3 seconds.

Step-by-step Explanation:

1. The average distance between the Earth and the Moon is approximately 384,400 kilometers, which is equal to 3.844 × 10⁸ meters.

2. The speed of light in a vacuum is approximately 300,000 kilometers per second, or 3 × 10⁸ meters per second.

3. To find the time taken for sunlight reflected from the lunar surface to travel to Earth, we use the distance-speed-time relationship:

$\text{Time}=\frac{\text{Distance}}{\text{Speed of Light}}$

Substituting the values into the formula:

$\text{Time}=\frac{3.844\times {10}^8\text{m}}{3\times {10}^8\text{m/s}}\approx 1.28\text{seconds}$

4. Rounding 1.28 seconds to one decimal place gives approximately 1.3 seconds. Hence, reflected sunlight from the Moon takes about 1.3 seconds to reach Earth.
