Answer:

30 minutes

Step-by-step explanation:

She plays 1/2 of a song in 1/4 of a minute so that would be 15 minutes because if you divide 60 by 4 you would get 15. You would multiply 15 by 2 because if she plays a full song you multiply 1/2 by 2 to get a whole. So she will need 30 minutes to play a full song

Answer:
Half a minute
30 seconds

Because if half the song is played in 15 seconds then you double that to get 30 seconds and a full song
