Algebra.Com's Answer #620765 by Theo(13342)![]() ![]() You can put this solution on YOUR website! for every hour that the plan flies, it is traveling 590 miles.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "for that same hour, the wind is traveling in the opposite direction for r miles.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "that means that the wind is pushing the plane back r miles for every 590 miles is is going forward.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "the net progress of the plane is therefore 590 - r miles per hour.\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
