On a hot day in the desert (T = 46 °C), a sound of 496 Hz is emitted by a drone travelling at 139 km/h toward a person in a dune buggy. If the sound frequency received by the person is 566 Hz, determine the speed of the dune buggy (in km/h). Provide a positive answer if the dune buggy is travelling toward the drone, and a negative answer if the dune buggy is travelling away from the drone.
