Answer: It will take about 21,689 years.
To start, we need to know that there are 9.5 x 10^12 kilometers in a light year. Next, lets divide that by 50,000 (or 5 x 10^4) to find the number of hours that it will take to travel that distance.
9.5 x 10^12 5 x 10^4 = 1.9 x 10^8 hours
We could further divide that be 24 to find the number of days and then by 365 to find the number of years.
1.9 x 10^8 / 24 / 365 = 21,689 years
It will take about 21,689 years.
