1. **State the problem:** We are given that the time shown is 25 minutes faster than the time in Trinidad. The time in London is 4 hours ahead of Trinidad. We need to find the correct time in London when the shown time is 8:35 am. 2. **Find the actual time in Trinidad:** The shown time is 8:35 am, which is 25 minutes faster than Trinidad time. So, Trinidad time = shown time - 25 minutes $$8:35 - 0:25 = 8:10\ \text{am}$$ 3. **Calculate the time in London:** London is 4 hours ahead of Trinidad. So, London time = Trinidad time + 4 hours $$8:10 + 4:00 = 12:10\ \text{pm}$$ 4. **Final answer:** The correct time in London at that moment is **12:10 pm**.
