\n" ); document.write( "\n" ); document.write( " Let Plane speed= x mph
\n" ); document.write( " let wind speed= y mph
\n" ); document.write( " with wind , speed= (x+y)
\n" ); document.write( " against wind, speed (x-y)
\n" ); document.write( " d= 7056 with wind d/s =t
\n" ); document.write( "
\n" ); document.write( " 7056 / (x+y) = 8
\n" ); document.write( " divide by 8
\n" ); document.write( "
\n" ); document.write( " 882 / (x+y) = 1
\n" ); document.write( " (x+y) = 882 ............1
\n" ); document.write( "
\n" ); document.write( " d= = 6096 against wind
\n" ); document.write( " 6096/(x-y) = 8
\n" ); document.write( " divide by 8
\n" ); document.write( "
\n" ); document.write( " 762 /(x-y) = 1
\n" ); document.write( " x - y = 762 .............2
\n" ); document.write( " add up (1) & (2)
\n" ); document.write( " 2 x = 1644
\n" ); document.write( " / 2
\n" ); document.write( " x= 822 mph speed of Plane in still air
\n" ); document.write( "
\n" ); document.write( " plug value of x in (1)
\n" ); document.write( " we get y= 60 mph speed of wind
\n" ); document.write( " \n" ); document.write( "
