Algebra.Com's Answer #216676 by mananth(16946)![]() ![]() You can put this solution on YOUR website! Trains A and B are traveling in the same direction on parallel tracks, train A is traveling at 40mph B at 50mph. Train a passes the station at 5:15 am train B passes same station at 5:45am at what time will train B catch up to train A. I just need this information put into the equations used for this problem (formulas) I will be able to get the answer from there.\r \n" ); document.write( "\n" ); document.write( "Let the distance where they meet be x from 5.45 am\r \n" ); document.write( "\n" ); document.write( "Train A takes x/40 to reach their meeting place\r \n" ); document.write( "\n" ); document.write( "Train B takes x+20/50 to reach their meeting place\r \n" ); document.write( "\n" ); document.write( "x/40 = x+20 /50 \n" ); document.write( "50x=40(x+20)\r \n" ); document.write( "\n" ); document.write( "50x-40x=800\r \n" ); document.write( "\n" ); document.write( "10x= 800\r \n" ); document.write( "\n" ); document.write( "x= 80 miles\r \n" ); document.write( "\n" ); document.write( "x+20 = 100 miles \r \n" ); document.write( "\n" ); document.write( "Train B travels 50 mph.
