Solve the all parts of given question:

Question: A train whistle is heard at 290Hz as the train approaches town. The train cuts its speed in half as it nears the station, and the sound of the whistle is then 280 Hz.

Part A: What is the speed of the train before slowing down?

Part B: What is the speed after the train slows down?

Please break down every step and do not skip over anything - I have been at this problem awhile and keep getting hung up. Thanks for the help!
