A jet flying at an altitude of 35,000 ft passes over a small plane flying at 10,000 ft headed in the same direction.
\n" ); document.write( " The jet is flying twice as fast as the small plane, and 30 mins later they are 100 mi apart.
\n" ); document.write( " Find the speed of each plane.
\n" ); document.write( ":
\n" ); document.write( "Their difference in flight paths are 25,000 ft which is 4.7 mi apart but that is not enough to make a difference in the way we solve this problem.
\n" ); document.write( ":
\n" ); document.write( "let s = the speed of the slower plane
\n" ); document.write( "then
\n" ); document.write( "2s = the speed of the jet
\n" ); document.write( ":
\n" ); document.write( "Write a distance equation, dist = time * speed
\n" ); document.write( "\"1%2F2\"*(2s-s) = 100
\n" ); document.write( "2s - s = 200
\n" ); document.write( "s = 200 mph is speed of the slower plane
\n" ); document.write( "then obviously
\n" ); document.write( "400 mph is the speed of the jet
\n" ); document.write( "
\n" ); document.write( "
\n" );
