document.write( "Let x represent the amount of time  before the plane overtakes the car
\n" );
document.write( "D = r*t, distance traveled the same for both car and plane
\n" );

document.write( " 80mph(x + 1hr) = 400mph*x
\n" );
document.write( "solving for x
\n" );
document.write( "        80 = 320x
\n" );
document.write( "         x = 1/4hr, the amount of time  before the plane overtakes the car
