A source of sound moves towards an observer

At what speed should a source of sound move away from a stationary observer so that observer finds the apparent frequency equal to half of the original frequency?

A source of sound is moving with a velocity of 50ms^(-1) towards a stationary listener. The listener measures the frequency of the source as 1000Hz. What will be the apparent frequency of the source when it is moving away from the listener after crossing him? (velocity of sound in the medium is 330ms^(-1) ).
