When the two cars meet, they will have traveled a combined 190 miles.
\n" ); document.write( "d = 190 miles
\n" ); document.write( ".
\n" ); document.write( "t = 2 hr for both of them (given)
\n" ); document.write( ".
\n" ); document.write( "One car goes at rate = r.
\n" ); document.write( ".
\n" ); document.write( "The other goes at rate = r-5.
\n" ); document.write( ".
\n" ); document.write( "2r + 2(r-5) =190
\n" ); document.write( ".
\n" ); document.write( "2r +2r -10 = 190
\n" ); document.write( "4r = 200
\n" ); document.write( "r = 50
\n" ); document.write( ".
\n" ); document.write( "r-5 = 45
\n" ); document.write( ".
\n" ); document.write( "Answer: The cars travel at at average speeds of 50 mph and 45 mph.
\n" ); document.write( ".
\n" ); document.write( "Check the answer to see if they cover 190 miles combined.
\n" ); document.write( "2*50 = 100 miles
\n" ); document.write( "2*45 = 90 miles
\n" ); document.write( "Correct.
\n" ); document.write( ".
