A weather drone tracking a storm cloud emits a continuous acoustic signal of frequency \(800 \text{ Hz}\) as it moves along a straight line toward or away from a stationary weather station. The station detects the arriving sound signal at a frequency of \(850 \text{ Hz}\). Assuming the speed of sound in air is \(340 \text{ m/s}\), which of the following correctly identifies the direction of motion of the drone relative to the station and its speed?
