let the speed of slower car be x
\n" ); document.write( "the speed of car II = x+6\r
\n" ); document.write( "\n" ); document.write( "They meet after 1 hour after car I starts\r
\n" ); document.write( "\n" ); document.write( "distance by car I = x
\n" ); document.write( "distance by car II = (x+6)*3/4........... ( speed * time)\r
\n" ); document.write( "\n" ); document.write( "x+3/4(x+6)=92\r
\n" ); document.write( "\n" ); document.write( "multiply by 4
\n" ); document.write( "4x+3(x+6)=368\r
\n" ); document.write( "\n" ); document.write( "4x+3x+18=350
\n" ); document.write( "7x=350
\n" ); document.write( "x=50 \r
\n" ); document.write( "\n" ); document.write( "50 & 56mph
\n" ); document.write( "
