Distance = speed * time; therefore,
time = Distance / speed.

Find the distances between these pairs of bodies, and divide that by the speed of light and you'll have the time.

The rest is left as an exercise for the student. Good luck!

If you travel at the speed of light and talking about time (or distance), you must specify whose time you are trying to measure.

According to the theory of relativity, if you are the astronaut traveling at the speed of light, your time will stop with respect to the time on Earth, and you will reach any of the 3 destinations instantly.

If you are observing the spaceship from Earth, see other people's answers for the times of travel.

As an interesting side effect, if you could travel at the speed of light, you could (in your time frame) instantly arrive to stars that are millions of light years away, but when you'd come back home (theoretically moments later), you'd find that the Earth would be millions of years older.

But, as others pointed out, reaching the speed of light is impossible.

earth to sun, 8 minutes 20 seconds
earth to moon, 1 minute 20 seconds

to figure out the rest, take the distances (in miles) and divide them by 186,000 miles per second

I would never be able to travel at the speed of light

A. We simply cannot travel that fast.

B. If you want to assume that I am going .99999c it would take:
1) 3 days
2) 3 minutes
3) 144 days
4) 892 years

accounting for time dilation

If you want to assume .999999999c, multiply each time by 10

186,000 divided by 93 million miles equals time it would take you to sun
Use the same calculations to determine time it would take you to go to other destinations.
