Algebra.Com's Answer #91434 by checkley71(8403) ![]() You can put this solution on YOUR website! the faster car=3(r+10) \n" ); document.write( "the slower car=3.5*r \n" ); document.write( "seeing as the distances are the same we set these 2 equations equal to each other. \n" ); document.write( "3(r+10)=3.5r \n" ); document.write( "3r+30=3.5r \n" ); document.write( "3r-3.5r=-30 \n" ); document.write( "-.5r=-30 \n" ); document.write( "r=-30/-.5 \n" ); document.write( "r= 60 mph is the speed of the slower car. \n" ); document.write( "60+10=70mph is the speed of the faster car. \n" ); document.write( "distance=3*70=210 miles. \n" ); document.write( "distabce=60*3.5=210 miles.\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
