\n" ); document.write( "12T=15(4.5-T)
\n" ); document.write( "12T=67.5-15T
\n" ); document.write( "12T+15T=67.5
\n" ); document.write( "27T=67.5
\n" ); document.write( "T=67.5/27
\n" ); document.write( "T=2.5 HOURS FOR THE 12 MPH. TRIP.
\n" ); document.write( "12*2.5=30 MILES IS THE DISTANCE.
\n" ); document.write( "15(4.5-2.5)=15*2=30 MILES DITTO.\r
