how many minutes is to

The phrase "how many minutes is to" appears to be incomplete and ambiguous. If the question is about how many minutes are in a specific unit of time (such as how many minutes are in an hour), the answer is: There are 60 minutes in one hour. If the intent was different, such as asking for the number of minutes between two times or converting a specific amount of time to minutes, please provide more details for a precise answer. For now, the key information is that 1 hour equals 60 minutes.
