Explanation:

 At a school concert the orchestra plays 8 songs that are 4.25 min and 3 songs that are twice as long as each of the others.

 Total length of 8 songs = 4.25*8 = 34 min

 Length of 3 songs = 2*4.25 = 8.5 min

 Total length of 3 songs = 3* 8.5 = 25.5 min

Total time of the concert = 34 + 25.5 = 59.5 min =  59 minute 30 seconds
