Each hour has 60 minutes, so to find out the number of minutes in a given number of hours, just multiply the hours by 60.
For example, to find out how many minutes are in 1 day, we can do:
1 day = 24 hours;
24 hours x 60 minutes = 1,440
So we know that there are 1,440 minutes in a day.
Now if you have a time in hours and minutes and you want to know the total time in minutes, you first find the minutes based on the hours and then add the minutes, for example: 45:27 (Forty-five hours and twenty and seven minutes):
45 * 60 = 2,700
2,700 + 27 = 2,727 minutes.
We separate below a table with some values in hours and their representation in minutes, see:

| 6h | 360 min |
| 7h | 420 min |
| 8h | 480 min |
| 9h | 540 min |
| 10h | 600 min |
| 11h | 660 min |
