Two boats leave a port at the same time, one going north and other traveling south. The northbound boat travles 16 mph faster than the southbound boat. If the southbound boat is traveling at 47 mph, how long will it be before they are 1430 miles apart?

    okay so the first thing you want to do is compare the two and make a relationship

    there are two things that the boats have in common the the rate unit and the distance right

    so the formula that ties speed, time, and distance is d=st

    right

    distance = speed times time

    yeah, I forgot to put the formula

    time can also be represented as a rate in this case we have mph

    Okay so would you now set the equation up

  18. anonymous

    therefore it would be appropriate to say distance= speed times rate

    so one boat is going x mph the other boat is going 16+x

    x=47 and 16+47 is 63

    the only thing that ties these two boats together is the distance so we can assume the equation will be equal to 1430 or the distance

    the other side would be related because it shares a common unit the rate or mph

  25. anonymous

    therefore 1430=rt+rt

    the rates are 63 mph and 47 mph

    t = time

    so the final equation looks like 1430=63t+ 47t

    1430=110t

    1430/110=t
