Mostky for parts c and d, which values am I using for the different frequencies? I got the beat frequency for c and d to be the same answer and I don't think that's right...

The frequency of B observed by C will be higher than 400Hz. 

The frequency of B observed by A will be lower than 400Hz

The amount of the difference observed by A and C could be very similar depending on the number of significant digits. So it is possible that your answer may look the same but the equations to calculate them will be different.
