Solve the given question:

Question: A Metro train is moving toward the station at a speed of 25 m/s. (For perspective, 27m/s is about 60 mph) Its horn emits a sound of frequency 800 Hz.

Question 1: Calculate the frequency detected by a person standing still at the station. (Use 345 m/s for the speed of sound.)

Question 2: As the train moves away, still blowing its horn at the same frequency as before, the observer hears a frequency of 754 Hz. Calculate the new speed of the train.

I want complete calculation for help. Thanks.
