Think of one plane as not moving and the other
\n" ); document.write( "one flying at the sum of their speeds
\n" ); document.write( "Let $\"+s+\"$ = the speed of the slower plane
\n" ); document.write( " $\"+6000+=+%28+s+%2B+s+%2B+200+%29%2A5+\"$
\n" ); document.write( " $\"+6000+=+%28+2s+%2B+200+%29%2A5+\"$
\n" ); document.write( " $\"+6000+=+10s+%2B+1000+\"$
\n" ); document.write( " $\"+10s+=+5000+\"$
\n" ); document.write( " $\"+s+=+500+\"$
\n" ); document.write( " $\"+s+%2B+200+=+700+\"$
\n" ); document.write( "the speed of the slower plane is 500 mi/hr
\n" ); document.write( "check:
\n" ); document.write( " $\"+6000+=+%28+2s+%2B+200+%29%2A5+\"$
\n" ); document.write( " $\"+6000+=+%28+2%2A500+%2B+200+%29%2A5+\"$
\n" ); document.write( " $\"+6000+=+1200%2A5+\"$
\n" ); document.write( " $\"+6000+=+6000+\"$
\n" ); document.write( "OK
