D=RT
\n" ); document.write( "D1=R3 FOR CAR ONE.
\n" ); document.write( "D2=(R+12)3 FOR CAR TWO.
\n" ); document.write( "D1+D2=444
\n" ); document.write( "444=R*3
\n" ); document.write( "R=444/3
\n" ); document.write( "R=148
\n" ); document.write( "R+(R+12)=148
\n" ); document.write( "2R=148-12
\n" ); document.write( "2R=136
\n" ); document.write( "R=136/2
\n" ); document.write( "R=68 KM/HR. IS THE SPEED OF THE SLOWER CAR.
\n" ); document.write( "68+12=80 KM/HR IS THE SPEED OF THE FASTER CAR.
\n" ); document.write( "PROOF;
\n" ); document.write( "444=68*3+80*3
\n" ); document.write( "444=204+240
\n" ); document.write( "444=444
\n" ); document.write( "
