Question

Light takes about 8.3 minutes to travel from the Sun to Earth. When it is closest, Neptune is 30.0 times farther from Earth than the Sun is. How long does it take for light from the Sun to reach Neptune, measured in minutes?

Answer 1

it takes light approximately 0.25 minutes to travel from the Sun to Neptune.

Step-by-step explanation:

The distance from Neptune to the Sun is 30.0 times farther than from the Earth to the Sun, so it's 30.0 * 93 million miles = 2,790 million miles.

The speed of light is approximately 186,282 miles per second, so it takes light approximately 2,790 million miles / 186,282 miles/second = 14.97 seconds to travel from the Sun to Neptune.

Since there are 60 seconds in a minute, this is equivalent to 14.97 seconds / 60 seconds/minute = 0.25 minutes.

So, The distance from Neptune to the Sun is 30.0 times farther than from the Earth to the Sun, so it's 30.0 * 93 million miles = 2,790 million miles.

The speed of light is approximately 186,282 miles per second, so it takes light approximately 2,790 million miles / 186,282 miles/second = 14.97 seconds to travel from the Sun to Neptune.

Since there are 60 seconds in a minute, this is equivalent to 14.97 seconds / 60 seconds/minute = 0.25 minutes.

so it takes light approximately 0.25 minutes to travel from the Sun to Neptune.
