\n" );
document.write( "Hi
\n" );
document.write( "D = r*t  Or D/r= t  
\n" );
document.write( "Note: John and Pat will be driving the same amount of time
\n" );
document.write( "Let x represent the distance Jon travels, then (440mi-x) will be Pat's distance. 
\n" );
document.write( "
\n" );
document.write( "Cross mulitply to solve for x
\n" );
document.write( "28x = 60(440-x)
\n" );
document.write( "28x = 60*440 - 60x
\n" );
document.write( "88x = 60*440
\n" );
document.write( "x = 60*440/88
\n" );
document.write( "x = 300mi, distance Jon travels
\n" );
document.write( "300mi/60mph = 5hrs, the time it took them to meet\r
\n" );
document.write( "\n" );
document.write( "CHECKING OUR ANSWER
\n" );
document.write( "60MPH*5HR + 28MPH*5HR = 300MI + 140MI = 440MI \n" );
