Two planes left at the same time from two airports which are 4,500 miles apart and flew toward each other. In 5 hours, they passed each other. The rate of the fast plane was twice the rate of the slow plane. Find the rate of each plane.
\n" ); document.write( "-----------------
\n" ); document.write( "Their combined rates = 4500 miles/5 hrs = 900 mph
\n" ); document.write( "----------------
\n" ); document.write( "EQUATION:
\n" ); document.write( "Their rates are 2x and x
\n" ); document.write( "2x+x = 900
\n" ); document.write( "3x = 900
\n" ); document.write( "x = 300 mph (rate of slow plane)
\n" ); document.write( "2x = 600 mph (rate of fast plane)
