what was the speed of the wind?w = 450 - 375 = 75 mph-You are very welcome.......
it took 3 hours for a plane, flying against the wind, to travel 900 miles from alabama to minnesota. the "ground speed" of the plane is 300 miles per hour. on the return trip, the flight took only 2 hours with a ground speed of 450 miles per hour. during both flights the speed and the direction of the wind were the same. what was the speed of the plane in still air? what was the speed of the wind?

-
d = vt
v = speed in still air
w = wind speed
v - w = 300 mph
v + w = 450 mph
2v = 750
v = 375 mph
w = 450 - 375 = 75 mph

You are very welcome.
