Do you have the formula or equation to do that?

Is that value input by the user?
If so, use the same technique that the code uses to get the totalSec value from the user: print a message and use a Scanner class method to read the user's input.

One possible problem could be the code is doing int math:
40/60 = 0

40/60.0 = 0.66666666
