speed of 1 car is x, speed of other car is x+10
\n" ); document.write( "their combined speed is 2x+10 km/hr, and that equals 1200 km in 8 hours
\n" ); document.write( "so 8(2x+10)=1200, and the units are km on both sides (that must occur)
\n" ); document.write( "16x+80=1200
\n" ); document.write( "16x=1120
\n" ); document.write( "x=70 km/hr
\n" ); document.write( "x+10=80 km/hr
\n" ); document.write( "combined speed is 150 km/hr apart and that is 1200 km after 8 hours
\n" ); document.write( "
\n" );
