\n" ); document.write( "D=30T
\n" ); document.write( "D=40(T-4)
\n" ); document.write( "SEEING AS THE 2 DISTANCES ARE THE SAME THEN:
\n" ); document.write( "30T=40(T-4)
\n" ); document.write( "30T=40T-160
\n" ); document.write( "30T-40T=160
\n" ); document.write( "-10T=-160
\n" ); document.write( "T=-160/-10
\n" ); document.write( "T=16 HOURS THEY WILL MEET.
