Algebra.Com's Answer #639943 by fractalier(6550)![]() ![]() You can put this solution on YOUR website! Call the slower car's rate, r. The faster is moving at r+5. \n" ); document.write( "Now rate times time equals distance, or rt=d. \n" ); document.write( "The time is 3 hours for each car. \n" ); document.write( "Thus we can write \n" ); document.write( "3r + 3(r+5) = 495 \n" ); document.write( "3r + 3r + 15 = 495 \n" ); document.write( "6r + 15 = 495 \n" ); document.write( "6r = 480 \n" ); document.write( "r = 60 miles per hour \n" ); document.write( "r+5 = 65 miles per hour \n" ); document.write( " |
