at what point means distance:

at what distance should an object start to slow down if it starts going 10 and slows down at a rate of 10% and needs to stop at the exact point 1024.

This is an equation i'm trying to put in c-script, but I have to know the equation to put in first :P (if that makes any sense). I'm not sure about units, because that's all the info I have for the equation.
