Answer:
9:00 am -------------------- 12:00pm ( There are 180 minutes between them)
Go 48 minutes back (132 Minutes between them)
That time is divided by 2
(4x minutes past 9:00 and x minutes left to reach 12:00)
132/3 = 44 minutes are left
OR
12:00- 44 minutes = 11:16
11:16-48 minutes =10:28
9 am + 88minutes (44 x 2) = 10:28
