An airplane flying headwind travels the 1800 mile flying distance between two cities in 3 hours and 36 minutes. One the return flight, the distance is traveled in 3 hours. Find the air speed of the plane and the speed of the wind, assuming that both remain constant. \n" ); document.write( "------------------------- \n" ); document.write( "Against wind DATA: \n" ); document.write( "distance = 1800 miles; time = (216/60) hrs ; rate = d/r = 500 mph \n" ); document.write( "----- \n" ); document.write( "With wind DATA: \n" ); document.write( "distance = 1800 miles ; time = 3 hrs ; rate = d/r = 600 mph \n" ); document.write( "--------------------- \n" ); document.write( "Equations: \n" ); document.write( "p + w = 600 \n" ); document.write( "p - w = 500 \n" ); document.write( "--- \n" ); document.write( "2p = 1100 \n" ); document.write( "p = 550 (speed of the plane in still air \n" ); document.write( "--- \n" ); document.write( "p + w = 600 \n" ); document.write( "w = 50 mph (speed of the wind current) \n" ); document.write( "========================================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
