How long would it take light from the sun to reach Uranus?

Light ravels 300,000 Kilometer per second in vacuum.This come to about 5.4722 hours .

Speed of light 300,000KM/sec. You will get 4.16 hours or 250 minutes.

Divide this by 300,000. We get 79.3 seconds. 300,000 speed of light in vacuum.

778.million divided by 300,000.= 43.25 minutes.

Light travels at 300,000 kilometers/second. About 12 minutes.is the answer.

The distance between and varies a little, but if we use the approximation $93$ million miles and approximate the speed of light as $186000$ miles per second, then it takes:...

so divide this by speed of light 300,000 KM.sec. 108200,000/300,000= 360.6 seconds or 6.0 minutes.

The orbit of Mercury is highly eccentric. The orbit eccentricity is about 12 times Earth's Light second = 299192.458 km. From Planetary Fact Sheet, NASA, Aphelion = 69.8 million...

This is calculated using the following formula. z = c * t Where, z is the distance to the object. c is the speed of light. t is the time...

The speed of light (in a vacuum) is exactly $299792458$ metres per second (by definition) There are exactly $1609.344$ metres in each mile. So the fastest possible time to travel...
