Algebra.Com's Answer #144831 by bhayzone(8)![]() ![]() ![]() You can put this solution on YOUR website! Let, \n" ); document.write( "r = rate of the slower driver. \n" ); document.write( "r+30 = rate of faster driver.\r \n" ); document.write( "\n" ); document.write( "In 6 hours, \n" ); document.write( "Slower driver drives 6*r miles (dist = rate*time) \n" ); document.write( "Faster driver drives 6*(r+30)\r \n" ); document.write( "\n" ); document.write( "Totally between them they driver 600 miles. \n" ); document.write( "Thus, \n" ); document.write( "6*r + 6*(r+30)=600 \n" ); document.write( "Solving for r, we get \n" ); document.write( "r (slover drivers rate) = 35 mph \n" ); document.write( "r+30 (faster driver rate)= 65mph \n" ); document.write( " \n" ); document.write( " |
