Answer:
The correct answer is 4 pm.
Explanation:
Concept:
As we know that Greenwich Meridian Time (GMT) is located at 0° longitude.
- When we move towards the east of GMT, it takes 4 minutes
i.e: Time taken to cross 1° East longitude = +4 minutes.
→ (1°West longitude = -4 minutes)
- It means that as we move towards the east of GMT, and time increases.
→ While, when we move towards the west of GMT, time decreases.
Solution:
- As given, Time at GMT = 12 noon.
- The place is situated at 60°East longitude.
- From the above concept, we know that 1° East longitude = 4 minutes ahead.
- Therefore, 60°East longitude = 4 x 60 = 240 minutes ahead.
- Here, 240 minutes = 4 hours.
- Hence, Required time at given place = 12 noon + 4 hours = 4 pm.
