Question

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

Answer 1

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
