Algebra.Com's Answer #707821 by greenestamps(13208) You can put this solution on YOUR website! Another nice algebraic solution from Boreal... \n" ); document.write( "But let's see if a more informal solution makes sense to you. \n" ); document.write( "The stations are 306km apart; one train travels twice as fast as the other. That means that, at the time the trains pass each other, the faster train has covered 2/3 of the distance and the slower train has covered 1/3 of the distance. \n" ); document.write( "2/3 of the 306km for the faster train is 204km; since both trains traveled for 3 hours before they passed each other, the speed of the faster train is 204/3 = 68km/hr. And then the speed of the slower train is half of that, or 34km/hr. \n" ); document.write( " |
