\n" ); document.write( "Leah travels 270 km. Deb travels 250 km in the same time. Leah drives 4 km/h faster. what \"highlight%28speed%29\" are they each travelling at ?

\r\n" );
document.write( "Let x be Leah' speed in \"km%2Fh\".\r\n" );
document.write( "Then Deb' speed is (x-4) \"km%2Fh\".\r\n" );
document.write( "\r\n" );
document.write( "The equation is \r\n" );
document.write( "\r\n" );
document.write( "\"250%2F%28x-4%29\" = \"270%2Fx\".\r\n" );
document.write( "\r\n" );
document.write( "To solve it, multiply both sides by x*(x-4). You will get\r\n" );
document.write( "\r\n" );
document.write( "250x = 270*(x-4),\r\n" );
document.write( "\r\n" );
document.write( "250x = 270x - 1080,\r\n" );
