Minutes are problematic for a different reason, but hours would work. I think 110 minutes can count as either "handu" hour or "duse" hour - after all they aren't supposed to be exact measures. (The reason minutes don't work is that Korean has two different sets of numerals, native and Chinese, and minutes only work with Chinese numerals.)
