.
<pre>

Let x be the distance under the question.


It means that he just traveled x miles and 125-x miles left to travel.


From the condition, you have this proportion


    {{{x/(125-x)}}} = {{{2/3}}}.


From the proportion


    3x = 2*(125-x),

    3x = 250 - 2x

    3x + 2x = 250

    5x      = 250

     x      = 250/5 = 50.
