It is 111 minutes before noon, or 10:09 am
Step-by-step explanation:
Convert all terms to minutes:
12 noon = 12 x 60 = 720 minutes
10 am = 10 x 60 = 600 minutes
Let x denotes number of minutes before noon
The time now is 12 noon -x = 720 -x minutes
9 minutes ago it was 720-x-9
720 -x - 9 = 600 + 2x
720-9-600 = 3x
x = 111 minutes
It is 111 minutes before noon, or 10:09 am
