How fast should a car move toward you for the car's horn to sound 2.88% higher in frequency than when the car is stationary? The speed of sound is 343 m/s.
A)42.5 Hz
B)54.5 Hz
C)61.8 Hz
D)65.4 Hz
v=16
fs=583
vs=343
(16+0)/16
Im not even gonna post the rest because quite frankly I don't get it

The choices don't even make sense. Answers given are in hz, and the problem asks for velocity. Something is major wrong.
