How long would it take to travel to the farthest known galaxy?

The distance is usually measured in light years, the distance light will travel in a year. If you take this distance in light years and multiply it by the number of times that light is faster than your speed that would give you the time it would take. Let us assume we could travel at 300 meters per second. This is about 750 miles per hour. Then light moves 1 million times faster than we do. The nearest star is four or five light years away, so it would take about 4 million years to get there. You can look up the distances to your favorite galaxy.
