Let speed (rate) of slower car be S
\n" );
document.write( "Then speed (rate) of faster car = S + 10
\n" );
document.write( "Time slower car takes to cover 60 miles: 
\n" );
document.write( "Time faster car takes to cover 90 miles: 
\n" );
document.write( "We then get the following TIME equation: 
\n" );
document.write( "90S = 60(S + 10)------ Cross-multiplying
\n" );
document.write( "90S = 60S + 600
\n" );
document.write( "90S - 60S = 600
\n" );
document.write( "30S = 600
\n" );
document.write( "S, or speed (rate) of slower car = , or  
\n" );
document.write( "Add 10 to this speed (rate) to get speed (rate) of faster car. \n" );
document.write( "

\n" );
