In how much time does moonlight reach the Earth?

Options

A. 1.3 seconds
B. 13 seconds
C. 1.3 minutes
D. 13 minutes

Answer

To determine how much time moonlight takes to reach the Earth, we can follow these steps:

### Step 1: Understand the speed of light
The speed of light in space is approximately 186,000 miles per second.

### Step 2: Know the distance from the Moon to the Earth
The average distance from the Moon to the Earth is about 250,000 miles.

### Step 3: Use the formula for time
To find the time it takes for light to travel a certain distance, we can use the formula:
\[ \text{Time} = \frac{\text{Distance}}{\text{Speed}} \]

### Step 4: Plug in the values
Using the distance of 250,000 miles and the speed of light (186,000 miles per second), we can calculate the time:
\[ \text{Time} = \frac{250,000 \text{ miles}}{186,000 \text{ miles/second}} \approx 1.34 \text{ seconds} \]

### Step 5: Round the answer
Since we are looking for a simplified answer, we can round 1.34 seconds to approximately 1.3 seconds.

### Conclusion
Therefore, the time it takes for moonlight to reach the Earth is about **1.3 seconds**.
