Question: A car moving at ( 3 5 mathrm { ~m } / mathrm { s } ) approaches a stationary whistle

A car moving at \(35\mathrm{~m}/\mathrm{s}\) approaches a stationary whistle that emits a 220 Hz sound. The speed of sound is \(343\mathrm{~m}/\mathrm{s}\). What is the speed of the sound relative to the driver of the car?
340 m/s
378 m/s
300 m/s
308 m/s
365 m/s
