Explanation:
You first need to convert everything to minutes:
12 noon = 12 x 60 = 720 minutes
9 am = 9 x 60 = 540 minutes
Let x = number of minutes before noon
The time now is 12 noon -x = 720 -x minutes
48 minutes ago it was 720-x-48
720 -x - 48 = 540 + 2x
720-48-540 = 3x
x = 44 minutes
It is 44 minutes before noon, or 11:16 am
