Let n be the speed of the local bus. Then the express bus would be n+10. So:
\n" ); document.write( "240/n-250/(n+10)=1
\n" ); document.write( "240n+2400-250n=nē+10n
\n" ); document.write( "nē+20n-2400=0
\n" ); document.write( "(n+60)(n-40)=0
\n" ); document.write( "n=40 or -60
\n" ); document.write( "The local bus travels 40 mph; the express bus travels 50 mph. ☺☺☺☺
\n" ); document.write( "
\n" );
