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( " \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( " |
