Passengers in an auto traveling at 16.0 m/s toward the east hear a siren frequency of 950

Question:

Passengers in an auto traveling at 16.0 m/s toward the east hear a siren frequency of 950 Hz from an emergency vehicle approaching them from behind at a speed (relative to the air and ground) of 40.0 m/s. The speed of sound in air is 340 m/s.

(a) What siren frequency does a passenger riding in the emergency vehicle hear?

(b) What frequency do the passengers in the auto hear after the emergency vehicle passes them?
