Algebra.Com's Answer #13381 by Paul(988)![]() ![]() ![]() You can put this solution on YOUR website! Sicne one flew 60 miles faster than the other we write 60+x \n" ); document.write( "And for the slower we write x \n" ); document.write( "In 5 hours they flew 2800 so 5 times the sum of two planes\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "5(60+x+x)=2800 \n" ); document.write( "300+10x=2800 \n" ); document.write( "10x=2500 \n" ); document.write( "x=250\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "250+60=310\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Hence one plane flew at 250mph and the other flew at 310mph. \n" ); document.write( "Paul. \n" ); document.write( " |
