How many mins before 12 noon if one hour ago it was 3 times many mins after 8 am

Answer 1

If it is now x minutes before noon, then it is
(4 hours-x min) = 240-x minutes
after 8 am.

So,
240-x-60 = 3x
180 = 4x
x = 45

So, it is now 11:15
That is, 45 minutes before noon
One hour ago, it was 10:15, or 135 minutes after 8 am
