D=RT
\n" ); document.write( "D=6T
\n" ); document.write( "D=10(T-3)
\n" ); document.write( "THE 2 DISTANCES ARE EQUAL.
\n" ); document.write( "6T=10(T-3)
\n" ); document.write( "6T=10T-30
\n" ); document.write( "6T-10T=-30
\n" ); document.write( "-4T=-30
\n" ); document.write( "T=-30/-4
\n" ); document.write( "T=7.5 HOURS.
\n" ); document.write( "PROOF:
\n" ); document.write( "6*7.5=10(7.5-3)
\n" ); document.write( "45=1-*4.5
\n" ); document.write( "45=45
\n" ); document.write( "7.5-3=4.5 HOURS AFTER THE SECOND RIDER LEAVES THEY WILL MEET.
