Question 252840: A jet takes the same time to travel 2500 km with the wind as it does to travel 1900 km against the wind. If its speed relative to the air is 450 km/hr, what is the speed of the wind? Answer by richwmiller(17219) (Show Source):
You can put this solution on YOUR website! rt=d
t=d/r
the times are the same so we set them equal
x= speed of wind
2500/(450+x)=1900/(450-x)
