Answer:
It would take 15,000 seconds, or 250 minutes = 4 hours and 10 seconds.
Explanation:
In order to calculate the time it would take light from the sun to reach Neptune, we will make use of the given data, while noting that time = distance ÷ speed.
Given data:
distance = 4.5 billion km = 4,500,000,000 km (this is the distance between planet Neptune, and the sun).
speed = 300,000 km/s (this is the speed at which light travels).
Therefore, time = 4,500,000,000 ÷ 300,000 = 15,000 seconds = 250 minutes, or 4 hours and 10 seconds.
