two planes left an airport at noon. One flew east at a certain speed and the other flew east at twice the speed.. the planes were 2700 mi apart in 3 hours how fast was each plane flying?
\n" ); document.write( "-------------------------------------
\n" ); document.write( "1st plane DATA:
\n" ); document.write( "rate = r mph; time = 3 hrs ; distance = 3r miles
\n" ); document.write( "------------------------
\n" ); document.write( "2nd plane DATA:
\n" ); document.write( "rate = 2r mph ; time = 3 hrs ; distance = 6r miles
\n" ); document.write( "-------------------------------
\n" ); document.write( "Equation:
\n" ); document.write( "2nd plane distance - 1st plane distance = 2700 miles
\n" ); document.write( "6r - 3r = 2700 miles
\n" ); document.write( "3r = 2700
\n" ); document.write( "r = 900 mph (rate of the 1st plane)
\n" ); document.write( "2r = 1800 mph (rate of the 2nd plane)
\n" ); document.write( "=========================================
