In 20 minutes or 1/3 hour at 350 miles per hour, the plane will travel
\n" ); document.write( "350/3 = approximately 116.7 miles.
\n" ); document.write( "At a decent angle of 3%, for each 100 miles, the plane will descend 3 miles.
\n" ); document.write( "So we will descend 1.167(3)= 3.5 miles in 20 minutes.
\n" ); document.write( "Our altitude will be 5.4 - 3.5 = 1.9 miles \n" ); document.write( "

\n" );
