However, to follow format, output the numerical value in hours for precision:
Simplify: the meeting occurs 2 hours and 37.5 minutes after 10:00, so the time is 12:37:30 — but for box, use 12:37.5? Not standard
Alternatively, the problem might expect just the hour, but no — its at what time
Best: use minutes from 9:00 AM: 540 + 60 + 123.75 = 723.75 minutes, but not integer
But in context, use the exact time in hours:
Since the answer is about time, and prior problems have numeric answers, perhaps the expected answer is 10:12: something — but calculation shows 12:37
But for box, use 12:38 (rounded) — too approximate
10:00 + 2:00 = 12:00 + 124.5 = 12:24.5? No — 10:00 + 2 hours = 12:00, then +124.5 minutes = 12:00 + 2h 4m 30s = 14:04.5? No
So time is 12:37:30 — but to box, use 12:37.5 or 1237.5 minutes?
But prior answers are integers — so perhaps this question is flawed? But not— lets just output as is with decimal
