I put it there for a friend of mine who's a high-school teacher and she's doing an online scavenger hunt. I have no idea what it means, so it doesn't really matter to me if it's "correct" or not... This is from the question that leads to it:
-------------------------------------
You are travelling to a distant star 100 light-years away, at a constant speed that tells you the distance is only 25 light-years away. How many years, relative to you, will it actually take you to make the journey?
The equation to be used can be found [a bunch of scavenger hunt details here].
Hint: D is the spatial dilation percentage, derived from the time dilation equation t'/t. The distance change is the product of time dilation. D=v/t
If the answer to this question is not a whole number, round up to the nearest one. That whole number will be the next question you should follow. Good luck!

Knock yourself out. I took Algebra in college and got a C.
