Algebra.Com's Answer #653922 by jorel555(1290)![]() ![]() ![]() You can put this solution on YOUR website! Let r be the rate of the freight train. The passenger train goes r+15. So: \n" ); document.write( "245/r+15=200/r \n" ); document.write( "245r=200r+3000 \n" ); document.write( "45r=3000 \n" ); document.write( "r=66-2/3 \n" ); document.write( "r+15=81-2/3!!!!!!!!!!!!!!!!!!\r \n" ); document.write( "\n" ); document.write( "245/r is 245 divided by r, which represents the time taken by the freight train...... \n" ); document.write( "Cross-multiplying 245/(r+15)=200/r, we get: \n" ); document.write( "245r=200(r+15) \n" ); document.write( "245r=200r+3000 \n" ); document.write( "etc.......... \n" ); document.write( " |
