Explanation: To solve this problem, we need to understand the basic concept of time calculation, specifically how to add a duration to a given time. The problem states that the travel duration from Bangalore to Goa is 7 hours, and the departure time is 11:00 AM. We need to find the arrival time.
The process involves adding the travel duration to the departure time. Here are the steps:
1. **Identify the departure time**: The departure time is 11:00 AM.
2. **Identify the travel duration**: The travel duration is 7 hours.
3. **Add the travel duration to the departure time**: We add 7 hours to 11:00 AM.
Let's break down the addition:
- Starting from 11:00 AM, adding 1 hour brings us to 12:00 PM.
- Adding another hour brings us to 1:00 PM.
- Adding another hour brings us to 2:00 PM.
- Adding another hour brings us to 3:00 PM.
- Adding another hour brings us to 4:00 PM.
- Adding another hour brings us to 5:00 PM.
- Adding the final hour brings us to 6:00 PM.
Thus, the arrival time is 6:00 PM.
It is important to note that when adding hours to a time, we need to be careful about crossing the 12:00 PM (noon) boundary. In this case, we do not cross the boundary, so the calculation is straightforward. However, if the travel duration were longer, we would need to account for the transition from AM to PM or vice versa.
Understanding this concept is crucial for solving similar problems involving time calculations, which are common in various competitive examinations and real-life scenarios.
