DISTANCE=RATE*TIME
\n" ); document.write( "360=R(T+2)
\n" ); document.write( "270=RT SOLVING FOR R IN THIS EQUATION WE GET
\n" ); document.write( "R=270/T NOW SUBSTITUTING (270/T) FOR R IN THE FIRST EQUATION WE GET
\n" ); document.write( "360=(270/T)(T+2)
\n" ); document.write( "360=(270T+540)/T
\n" ); document.write( "360T=270T+540
\n" ); document.write( "360T-270T=540
\n" ); document.write( "90T=540
\n" ); document.write( "T=540/90
\n" ); document.write( "T=6 HOURS IS THE TIME FOR THE RETURN 270 MILE TRIP.
\n" ); document.write( "6+2=8 HOURS FOR THE FIRST TRIP WHICH TOOK 2 HOURS LONGER.
\n" ); document.write( "THE RATE IS
\n" ); document.write( "270/6=45 MPH
