document.write( "The total distance traveled was 740 km.
\n" );
document.write( "How far did she travel by bus?
\n" );
document.write( "bus time is t, and train time is (t+2)
\n" );
document.write( "D = rt
\n" );
document.write( "50t + 70(t+2)= 740km
\n" );
document.write( "120t = 600
\n" );
document.write( "  t = 5hrs by bus.
\n" );
document.write( "  D=rt = (50mi/hr)(5hrs) = 250mi
\n" );

\n" );
document.write( "70(t+2) + 50t = 740km

document.write( "490 + 250  = 740km  checks.
