The first solution posted overlooked the fact that John traveled for 2 hours and Wilbur for only one hour. Other than that, it is a simpler approach than used in the second response.

\n" ); document.write( "Correcting the oversight in the first response, we have
\n" ); document.write( "John traveling for 2 hours at speed x;
\n" ); document.write( "Wilbur traveling for 1 hour at speed x-12; and
\n" ); document.write( "at the end they are 159 miles apart. So

\n" ); document.write( "\"2%28x%29+%2B+1%28x-12%29+=+159\"

\n" ); document.write( "And, as was said in the first response, you should be able to finish from there.
\n" ); document.write( "
