Aparked car's horn (belonging to a musician) emits a concert a of frequency 440 on a day when the speed of sound is 342 m/s. you are in a car speeding along toward the parked car at a speed that makes the pitch appear to be a# (466hz). at what speed in meters per second are you traveling?

19.08 m/s

Explanation:

f = actual frequency emitted by the parked car's horn = 440 Hz

V = speed of sound = 342 m/s

f' = frequency of the horn observed by you = 466 Hz

v = speed of your car moving towards the parked car = ?

frequency of the horn observed by you is given as

v = 19.08 m/s

i don't know that i agree with that but what's the question ?
