I promise this is not homework. I’ve been out of school for 25 years.

No, this is rather embarrassingly related to an RPG I’m involved with. (Probably would’ve been better if I *had* pretended it was homework!)

Here’s the sitch. There’s a character who’s born on a planet outside our own solar system. Logically, this planet’s “years” are different in length from our own; it takes longer for her planet to revolve around its star than it does for Earth to revolve around the sun.

However, this character interacts with humans and is used to having to express age according to Earth’s timeframe.

An important milestone in this character’s life will occur when she reaches the age of 20 (on her planet), which I want to be equivalent to 25 Earth years.

Right now, she is 23 1/2 in Earth years. How old would she be on her planet?

I just can’t seem to wrap my head around the task of figuring out how many Earth days = 1 year on her planet. Too much Calculus! Or is it Algebra? Either way, I’m too crappy at math to figure out a formula for calculating this time/age discreprency.

The closest I could sorta come up with was 20n = 25(365). Is that right? Even if it is, how does that help me figure out her current age?

Help?
