If a minute were defined as a million seconds, we can calculate how many minutes would be in an hour by converting the number of seconds in an hour to the new definition of a minute.
In a standard hour, there are 60 minutes, and each minute has 60 seconds. Therefore, in a standard hour, there are:
60 minutes/hour * 60 seconds/minute = 3,600 seconds/hour.
If we redefine a minute as a million seconds, we can calculate how many minutes would be in an hour using the new definition:
3,600 seconds/hour * (1 minute / 1,000,000 seconds) = 0.0036 minutes.
So, if a minute were defined as a million seconds, there would be 0.0036 minutes in an hour.
