An ambulance driver traveling at 30.0 m/s (is equal to 67.1 mph) honks his horns he sees a motorist ahead on the highway traveling in the similar direction. The motorist hears a frequency of 392 Hertz and notices that his own speedometer reads 35.8 mph (is equal to 16.0 m/s). Find the frequency that the ambulance driver hears. (Speed of sound is 340m/s)
