Determine the beat frequency does mandy hear

Reference no: EM13513747

In parts of the midwestern United States, sirens sound when a severe storm that may produce a tornado is approaching. Mandy is walking at a speed of 1.20 m/s directly toward one siren and directly away from another siren when they both begin to sound with a frequency of 660 Hz. What beat frequency does Mandy hear? (Assume a temperature of 20° C.)

_____________Hz
