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.
