Rate*Time=Distance
\n" ); document.write( " $\"R%5Bw%5D%2AT=D%5Bw%5D\"$ Westbound plane
\n" ); document.write( " $\"R%5Be%5D%2AT=D%5Be%5D\"$ Eastbound plane
\n" ); document.write( " $\"D%5Bw%5D%2BD%5Be%5D=2250\"$ Total distance
\n" ); document.write( " $\"R%5Bw%5D%2AT%2BR%5Be%5D%2AT=2250\"$ Substitute
