Given :
A map shows that a star is 25 light years away.
To Find :
If you get in a ship and travel to this star at 0.95c, How far will the ship need to travel to reach this star.
Solution :
We know, 1 light year in km is given by :
[tex]1 \ light \ years = 9.46 \times 10^{12}\ km[/tex]
So, 25 light years is given by :
[tex]25 \ light \ years = 25 \times 9.46 \times 10^{12}\ km\\\\25 \ light \ years = 2.365 \times 10^{14} \ km[/tex]
Hence, this is the required solution.
