Against the wind a small plane flew 858 miles in 2 hours and 10 minutes. The return trip took only 1 hour and 50 minutes. What was the speed of the wind? What was the speed of the plane in still air?
\n" ); document.write( "--------------------
\n" ); document.write( "Against the wind DATA::
\n" ); document.write( "dist = 858 miles ; time = 2 1/6 = 13/6 hrs ; rate = 858/(13/6) = 396 mph
\n" ); document.write( "-----
\n" ); document.write( "With the wind DATA::
\n" ); document.write( "dist = 858 miles ; time = 1 5/6 = 11/6 hrs ; rate = 858/(11/6) = 468 mph
\n" ); document.write( "--------
\n" ); document.write( "Equation:
\n" ); document.write( "With:: p + w = 468
\n" ); document.write( "Against: p - w = 396
\n" ); document.write( "-----
\n" ); document.write( "Subtract to solve for \"w\":
\n" ); document.write( "2w = 72
\n" ); document.write( "wind = 36 mph
