The plane flies between a and B cities. The downwind speed is a kilometer per hour, the upwind speed is B kilometer per hour. The wind speed is x kilometer emergency

The plane flies between a and B cities. The downwind speed is a kilometer per hour, the upwind speed is B kilometer per hour. The wind speed is x kilometer emergency

x=1/2(a-b)

When the plane flies between cities a and B, the downwind speed is a kilometer per hour, and the upwind speed is B kilometer per hour, then the wind speed is a kilometer per hour______ Kilometers

Let the wind speed be x km / h. according to the meaning of the question: A-X = B + X, the solution is: x = a − B2, then the wind speed is a − B2 km / h. so the answer is: a − B2

When the plane flies between cities a and B, the downwind speed is a kilometer per hour, and the upwind speed is B kilometer per hour, then the wind speed is a kilometer per hour____ .

（a-b)/2

When the plane flies between cities a and B, the downwind speed is a kilometer per hour, and the upwind speed is B kilometer per hour, then the wind speed is a kilometer per hour______ Kilometers

Let the wind speed be x km / h. according to the meaning of the question: A-X = B + X, the solution is: x = a − B2, then the wind speed is a − B2 km / h. so the answer is: a − B2
