Professors Roberts and Jones, who lives 676 miles apart, are exchanging houses and jobs for the summer. They start out for their new locations at exactly the same time, and they meet after 6.5 hours of driving. If their average speeds differ by 4 mph, what are their average speeds?
\n" ); document.write( "

With slower speed being S, we get: 6.5S + 6.5(S + 4) = 676
\n" );
document.write( "Solve to get: Slower and faster speeds:  \n" );
document.write( "

\n" );
