A source of sound moves towards an observer

A source of sound moves towards an observe.

A source and an observer is approaching closer with a relative velocity of 40 ms^(-1) . If the true frequency of the source is 1200 Hz calculate the observed frequency under these conditions: (i) the source alone is moving (ii) the observer alone is moving. Take velocity of sound in air to be 340 ms^(-1) .
