Let S = Shane and K = Kori
S = 52 Hours when working alone
S and K Together = 39 Hours
K = ?
S and K Together = SK/(S+K) <-- Formula (We have reasoning to explain it based on on work rate concept!)
39 = 52K/(52 +K)

SAT in general is more popular, or so it seems, but the fact is that a lot of students do take ACT as well. And colleges consider both SAT and ACT results for admissions.
