    Really?  You have to resort to asking random strangers to do (possibly incorrectly) a simple speed-time-distance problem for you because you can't be bothered to think  on your own?  And then we wonder why not enough women take STEM courses in college.

    Next time you ask others to do your homework for you at least make sure that your teacher is not monitoring this and other Q&A sites like this one to catch cheaters.

    im gunna guess that this is not a serious question, based on the 8 hours/3000 miles thing, so will give it a not serious answer- 

    Answer = the parable of the flan and toad, a conversation on distance and intention!

    4 hours in each direction, which is 4•3600 sec

    340 m/s x 4•3600 s = 4896000 m or about 5000 km

    which is silly, that is 3000 miles.
