Answer 1

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 :

$1 \ light \ years = 9.46 \times 10^{12}\ km$

So, 25 light years is given by :

$25 \ light \ years = 25 \times 9.46 \times 10^{12}\ km\\\\25 \ light \ years = 2.365 \times 10^{14} \ km$

Hence, this is the required solution.
