Answer #1

is the velocity of waves in the medium;

is the velocity of the receiver relative to the medium; positive if the receiver is moving towards the source (and negative in the other direction);

is the velocity of the source relative to the medium; positive if the source is moving away from the receiver (and negative in the other direction).

in this case = 8.0
