You can put this solution on YOUR website! With a tail wind, a helicopter traveled 300 miles in 1hour and 40 min. The return trip against the same wind took 20 min longer. Find the wind speed and also the air speed of the helicopter.
---------------
Downwind ground speed was 300/(5/3) = 180 mph
Upwind ground speed was 300/2 = 150 mph
The airspeed is the average, (180+150)/2 = 165 mph
The windspeed is 15 mph

PS My helicopter didn't go that fast.
