Question 1064223: flying in still air, an airplane travels 550 km/h. it can travel 1200 kn with the wind in the same time that it travels 1000 km against the wind. find the speed of the wind Answer by jorel1380(3719) (Show Source):
You can put this solution on YOUR website! Let w be the speed of the wind. Then:
1200/550+w=1000/550-w
550000+1000w=660000-1200w
2200w=110000
w=50
The speed of the wind is 50 kph. ☺☺☺☺
