Algebra.Com's Answer #427842 by MathTherapy(10552)![]() ![]() You can put this solution on YOUR website! a train leaves a station and travels north at a speed of 75mph. four hours later, a second train leaves on a parallel track and travels north at 175mph. how far from the station will they meet.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Let distance from station be D \n" ); document.write( "Time taken by 1st train to travel to \"meeting\" point, equals time taken by 2nd train to travel to \"meeting\" point, plus 4, OR\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( "7D = 3D + 2,100 ------ Multiplying by LCD, 525 \n" ); document.write( "7D – 3D = 2,100 \n" ); document.write( "4D = 2,100 \n" ); document.write( "D, or distance from station = \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "You can do the check!!\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Send comments and “thank-yous” to “D” at MathMadEzy@aol.com \n" ); document.write( " |
