Algebra.Com's Answer #626173 by fractalier(6550) You can put this solution on YOUR website! Rate times time equals distance. \n" ); document.write( "Call the slower train's rate, r. \n" ); document.write( "The faster one is then r+14. \n" ); document.write( "The time is 4 hours and the total distance is 200 miles. \n" ); document.write( "So we write \n" ); document.write( "4r + 4(r+14) = 200 \n" ); document.write( "8r + 56 = 200 \n" ); document.write( "8r = 144 \n" ); document.write( "r = 18 mph \n" ); document.write( "r+14 = 32 mph \n" ); document.write( " |
