You have a work meeting that at 1:15 you arrived at 12:53 how many minutes early were you

12:53 to 1:00 = 7 mins

1:00 to 1:15 = 15mins

7 mins + 15 mins = 22 mins

So, you were 22 mins early for your meeting.

If you would like to know how many minutes early were you, you can calculate this using the following steps:

12:53 - 13:00 ... 7 minutes

13:00 - 13:15 ... 15 minutes

7 minutes + 15 minutes = 22 minutes

The correct result would be 22 minutes.
