Two airplanes start at the same time from airports 500 km apart. Each one flies with an airspeed of 200km/h directly toward the other airport. But one reaches its airport half an hour before the other plane reaches the other airport. How fast is the wind blowing?

    s = d/t ; t = d/s t = 500/200 t-.5 = 500/200
