\n" );
document.write( "Tom runs 5 miles per hour faster than Carl
\n" );
document.write( "Let  r AND (r+5) represent Carl's and Toms's speeds respectively
\n" );

\n" );
document.write( "Tom and Carl start 200 miles apart, running towards each other.
\n" );
document.write( "they meet after 10 hours
\n" );
document.write( "Note: d = rt 
\n" );
document.write( " rt + (r+5)t = 200
\n" );
document.write( " t[r +(r+5)] = 200
\n" );
document.write( " t = 200/(2r+5) = 10hrs
\n" );
document.write( "Solving for r
\n" );
document.write( "10(2r+5) = 200
\n" );
document.write( "   2r + 5 = 20
\n" );
document.write( "      2r = 15
\n" );
document.write( "       r = 7.5, carls speed, tom's speed is 12.5
