A plane is currently at 200 ft and its descending at 10 ft per minute. The path of the gliding plane can be given by the following equation,
\n" ); document.write( "y=-10x+200
\n" ); document.write( "where y is the height of the plane and x is the number of minutes.
\n" ); document.write( "In how many minutes will the plane land?
\n" ); document.write( "------
\n" ); document.write( "y is zero when the plane lands.
\n" ); document.write( "-----
\n" ); document.write( "Solve: -10x + 200 = 0
\n" ); document.write( "-10x = -200
\n" ); document.write( "x = 20 minutes
\n" ); document.write( "--------
