180t=810(t-2)
\n" ); document.write( "180t=810t-1,620
\n" ); document.write( "180t-810t=-1,620
\n" ); document.write( "-630t=-1,620
\n" ); document.write( "t=-1,620/-630
\n" ); document.write( "t=2.57143 hours after Marty left they will meet.
\n" ); document.write( "Proof:
\n" ); document.write( "180*2.57143=810(2.57143-2)
\n" ); document.write( "462.85=810*.57143
\n" ); document.write( "462.85=462.85
\n" ); document.write( "
