Question title is self explanatory.

If I'm accelerating at $2ft/s ^{2}$, how long does it take to reach $9.8MPH$?

This reads like a homework question, though if it is one I don't approve of the use of $ft$ and $MPH$. And as @Bernhard said: please show some work and tell us where you're having difficulties. – Wouter Feb 21 at 16:31
Convert miles per hour to feet per second, and go from there. I'm trying not to just give you the answer. – Mike Dunlavey Feb 21 at 16:39

Yeah, this site isn't a calculation service. P.S. @Wouter FYI the (un?)official policy of the site is that SI units are favored but not required. Personally I couldn't care less what units are used as long as the units are specified. – David Zaslavsky Feb 21 at 18:50
@DavidZaslavsky I don't really care either but I do prefer SI units because they are (or at least they try to be) less arbitrary than other units. My comment was mostly a personal conviction ("I don't approve"), which I guess isn't really relevant... But still, I would encourage everyone to use SI at least in classical mechanics. Anyhow, I shouldn't discuss this here, so I won't. – Wouter Feb 21 at 19:27

This question is unlikely to help any future visitors; it is only relevant to a small geographic area, a specific moment in time, or an extraordinarily narrow situation that is not generally applicable to the worldwide audience of the internet.
