\n" ); document.write( "

Let D be the distance between the cities
\n" );
document.write( "Then John's and Peter's speeds are: , respectively
\n" );
document.write( "We then get the following SPEED equation: 
\n" );
document.write( "2D = 3D - 120 ----- Multiplying by LCD. 6 
\n" );
document.write( "2D - 3D = - 120
\n" );
document.write( "Distance between the cities, or  \n" );
document.write( "

\n" );
