if the nearest Galaxy is 25,000 light-years away... how long would it take to get to that very same galaxy moving at 800,000,000,000,000?

D/R = T   ...so...

 

[5,878,000,000,000 Miles  *  25,000]  / 800,000,000,000,000MPH  = about  183.69 hours.....  [a little more than a week.....!!!]

In one hour light can travel=186,282miles X 60 X 60=670,615,200 MPH,

Since nearest galaxy is 25,000 light-years away, then we have to figure out the of miles to the galaxy.

So the number of miles from here to the galaxy is=146,864,728,800,000,000, or 1.46865 X 10^17 / 8.0 X 10^14=183.58 hours to get to the galaxy. But, remember the FASTEST speed in the universe is the speed of light!!. But even light travels ONLY about 670 million miles per hour. So that you can NEVER get to that galaxy in LESS than 25,000 years, even if you were able to travel at the speed of light, which you can never atain, because it's forbidden by the Laws of Physics. You chose a speed of 8 X 10^14MPH, which is more than a million times FASTER than the speed of light!!!!!!.
