31.52 what? We need the unit. Is it 31.52 hour? Second? Minutes? Also, what is time? We need the unit from and to.
If it's 31.52 hours to minute. Then you 31.52 * 60 = 1891.2 Minutes
If it's 31.52 minutes to hour. Then you 31.52 / 60 = 0.5253333.... hour
If your time is 00:00 and you just did 31.52 hours of something. Then the time would be:
(We want a number ranging between 0-24) so we do 31.52 - 24 = 7.52 This tells us that 24 hours has passed (ignore cause it brings us back to 00:00) and another 7 hours has passed and 0.52 hour. Then we find the minute: 0.52 * 60 = 31.2 minutes. So the final answer, the time, is 7:31 AM.
I don't know what you want.
