A twin-engined aircraft can fly 648 miles from city A to B in 3 hours with the wind and make the return trip in 6 hours against the wind. What is the speed of the wind?
\n" ); document.write( "...
\n" ); document.write( "distance = 648
\n" ); document.write( "time = 3 hours
\n" ); document.write( "speed with wind = 648/3 = 216 mph
\n" ); document.write( "speed of wind = x
\n" ); document.write( "...
\n" ); document.write( "against wind speed = 648/6 = 108 mph\r
\n" ); document.write( "\n" ); document.write( ",..
\n" ); document.write( "216-x=x+108
\n" ); document.write( "216-108=2x
\n" ); document.write( "108=2x
\n" ); document.write( "x= 58 mph wind rate
