If the fastest spacecraft built by humans goes 30 kilometers per second how long would this spacecraft take to cross the galaxy if it has to travel 100000 light years?

The Milky Way is approx 9.5x10^17 Km across. So, divide that by 30 Km/s and you'll get 3.16x10^16 seconds then divide by 60sec/min, divide that by 60min/hour, divide that by 24 hr/day, divide that by 365 day/year and you get about 1 billion years and some change (not including leap years, but when dealing with a number this big, it really doesn't matter does it?)
Hope that answers your question.

If light travels at 300000kmsec and the galaxy is 100000 light years wide how many kilometers is this?
Answer: 100,000 light years = 9.454e+17 km
At its nucleus the Milky Way Galaxy is about 100000 light-years wide and .?
The whole of the galaxy has a diameter of approx 100000 light-years, not just the nucleus! So it is not clear whether the question is about the galaxy or its nucleus.
How many years would it take a spacecraft traveling at the speed of light to cross the milky way galaxy?
The very fastest human-made spacecraft ever aren't out of this solar system yet, and they were launched in the 70s."Billions of years" is, if anything, an understatement.
Is the iPhone 5 now the fastest smartphone on the market?
No. The fastest smartphone is the samsung galaxy s3
What is the distance across the milky way galaxy?
Our Milky Way galaxy is 100,000 light years across.
What is the fastest t-mobile smartphone?
Samsung Galaxy s2
Why was spacecraft invented?
The Space craft was invented to enable man to explore the outer planets and galaxy's.
How long does it take for us to get out of the Milky Way galaxy?
That will depend on the speed of our spacecraft. At its current speed, the Voyager spacecraft will not make it out of the Milky Way galaxy within the expected lifetime of the universe, and certainly not before the Andromeda galaxy collides with the Milky Way galaxy about 3 billion years from now. In another thousand years, after we've had some time to study this, ask me again.
Which galaxy is the Orion nebula in?
The Orion nebula is part of our own galaxy (the Milky Way). The Orion nebula is about 1500 light-years away from us. Our galaxy is about 100000 light-years across.
