The time taken to reach the Neptune planet is 4.2 hours
<h3>What is the time taken?</h3>
We can see that the speed of light has the value of 6.7 * 10^8 miles per hour . We also know that the solar system is composed of the sun and the planets. The distance of the between the sun and mercury is 35,000,000 miles while the distance between the sun and Neptune is 2.8 x 10^9 miles.
This implies that the ratio of the distance from neptune to the sun and that of mercury to the sun is; 2.8 x 10^9 miles/3.5 * 10^7 miles hence Neptune is eight times farther from the sun than mercury.
The time taken for light to reach Neptune from the moon is;
Distance = 2.8 x 10^9 miles
Speed = 6.7 * 10^8
Time = 2.8 x 10^9 miles/6.7 * 10^8
= 4.2 hours
