You can put this solution on YOUR website!
Let d = the distance from the station to the catch-up point. Then from the formula t = d/r,
\n" ); document.write( " $\"d%2F125+-+d%2F175+=+2\"$ <==> $\"%282d%29%2F875+=+2\"$ $\"d%2F875+=+1\"$ , or d = 875 miles.
\n" ); document.write( "-------------------------------------------------------------------------------\r
\n" ); document.write( "\n" ); document.write( "There is yet another way of approaching this problem, and that is to let
\n" ); document.write( "t = time of travel of train 1 before the catch-up, and
\n" ); document.write( "t - 2 = time of travel of train 2 before the catch,
\n" ); document.write( "and then use the formula d = rt, to get the equation 125t = 175(t-2).
\n" ); document.write( "But this is indirect... \n" ); document.write( "

\n" );
