If it was 10 hours and 10 minutes, it's never 20. And if you add 50 minutes, the time becomes 11 (hours)Hide Hint Show Hint Hide Answer Show Answer

this is really hard to guess if there was no hint at all. A cool one though;)
I'm not sure it's really math. Anyway, 10:10 could be twenty if you're timing something that started at 2:10, twenty hours ago.
Wording is confusing. Add 50 to what? I thought 10 + 10 + 50?
