With a certain tail wind a jet aircraft arrives at its destination, 1,890 miles away, in three hours. Flying against the same wind, the plane makes the return trip in 3 3/8 hours. find the wind speed and the planes airspeed.\r
\n" ); document.write( "\n" ); document.write( "With the wind Data:
\n" ); document.write( " distance = 1890 miles; time=3 hrs; rate=1890/3=630mph
\n" ); document.write( "Against the wind Data:
\n" ); document.write( " distance = 1890 miles: time= 3.375 hrs; rate=1890/3.375=560mph
\n" ); document.write( "airspeed+wind=630mph
\n" ); document.write( "airspeed-wind=560mph
\n" ); document.write( "Add the two equations to get:
\n" ); document.write( "2(airspeed)=1190mph
\n" ); document.write( "Airspeed=595mph
\n" ); document.write( "Then wind=630-595=35mph
