We start qt 72 degrees,

3 1/5 = 16/5 = 3.2 x 10 minutes = 32 degrees.

72 + 32 = 104 degrees.

Cool Time:

4 2/7 = 30/7 = 4.28571429 x 7 minutes = 30 degrees.

104 - 30 = 74

So we went from 72 to 74 degrees, that is a 2 degree difference.

This is what i got, i hope i understood the question correctly. v
