document.write( "Let x and (x+4) represent the time the car and truck traveld respectively
\n" );
document.write( "Question states*** Note: D = r*t  (distance the same for both)
\n" );
document.write( "  55x = 45(x+4)
\n" );
document.write( "Solving for x
\n" );
document.write( "   10x = 180     
\n" );
document.write( "     x = 18hr, time car traveled.     
\n" );
document.write( "    55mph*18hr = 990mi, how far they traveled.
