van x miles per hour
\n" ); document.write( "car x+15 miles per hour
\n" ); document.write( "time=distance/rate
\n" ); document.write( " $\"126%2F%28x%2B15%29=99%2Fx\"$ cross multiply
\n" ); document.write( " $\"126x=99%28x%2B15%29\"$
\n" ); document.write( " $\"126x=99x%2B1485\"$
\n" ); document.write( " $\"27x=1485\"$ divide both sides by 27
\n" ); document.write( " $\"x=55\"$ so vans speed is 55 mph
\n" ); document.write( "then car's speed is 55+15=70 mph \n" ); document.write( "

\n" );
