The model A CD burner burns 60 minutes of data in about 1.15 minutes. The model B CD burner burns 60 minutes of data in about 1.5 minutes. How much longer will it take to burn 80 minutes of data onto a CD using the model B burner than using the model A burner?

1.15/3 = 20 minutes worth = 0.383 60 minutes+20 minutes=80 minutes = 1.15+0.383=1.53
1.5/3 = 0.5 = 20 minutes 60 minutes+20 minutes=80 minutes =1.5+0.5=2
2-1.53=0.47 therefore it is 0.47 minutes quicker with Model A
