Two trains approach each other on separate but adjacent tracks. Train 1 is traveling at a speed of 29.9 m/s and train 2 at a speed of 21.6 m/s. If the engineer of train 1 sounds his horn which has a frequency of 520 Hz, determine the frequency of the sound heard by the engineer of train 2. (Use 343 m/s as the speed of sound. Enter your answer to the nearest Hz.)______ Hz
