Hi Vanetta, to find the difference between 3y minutes and 25y seconds, you have to convert 3y minutes into seconds first. Simply multiply 3y by 60 = 120y. You can then find the difference which is 120y-25y=95y secs.
For the second part, it is the same concept. Convert everything into seconds by multiplying the mins by 60 and hours by 60x60.
