Suppose you have a broken 12-hour digital clock that has its display turned on only when the number of hours is the same as the number of minutes - 08:08, 09:09, 10:10, and so on.
What is the minimum time interval between such two “neighboring“ turnings?
What is the minimum time interval between such two “neighboring“ turnings?
Explanations
Subtracting the “previous“ hour from the “next“ one, we will constantly get the 61 minutes difference as a result. But if we consider “12:12“ as the previous number and subtract it from the following “01:01“ we will get much better result and, thus, significantly less interval - 49 minutes.Check 49 mins
