    in minutes it would be t/25=t amount of minutes. ex. if the test took 5 hors the first thing you would do is 60x5(which equals 300 btw) then you would just do 300/25 which equals 12 Hours are a bit trickier. I think that because there are 60 mins in one hour and thirty mins in a half hour, it would be either 60/25 or 30/25. 30/25=1.2 and 60/25 is double the ammount (2.4)

    not really, because we dont know what "t" is, so its an open equation ( t/25=t amount of minutes.) however, i dont know if they count half hours and/or whole hours, so i put in the half hour and the whole hour that way i can count both
