PHYSICS!!!HELP！！

An aircraft carrier has a speed of 13.0m/s relative to the water. A jet is catapulted from the deck and has a speed of 67.0m/s relative to the water. The engines produce a 1550-Hz whine, and the speed of sound is 343m/s. What is the frequency of the sound heard by the crew on the ship?

CAN ANYONE PLEASE GIVE ME SOME IDEAS TO DO IT?THANKS A LOT!!!
