Final answer:
The time in Gujarat would officially be 7:00 am if it is 7:00 am in Arunachal Pradesh, as India follows a single time zone - Indian Standard Time. Geographical longitudes suggest a natural time difference, but it is not officially recognized in daily life across the country.
Step-by-step explanation:
If we want to calculate the local time difference between Arunachal Pradesh and Gujarat, we must consider India's vast longitudinal extent which affects the local time. India has only one time zone known as Indian Standard Time (IST), which is based on the longitude passing through 82.5°E. As a result, the entire country follows the same standard time without any official difference between the states. However, if we consider the geographical difference in longitudes, there will be a slight local time difference due to the fact that time changes by approximately 4 minutes for every degree of longitude.
Arunachal Pradesh is located near the eastern border of India, whereas Gujarat is situated near the western edge. This geographical span covers a significant difference in longitudes. Depending on the specific locations within these states, there could be a difference of nearly two hours. But for simplicity, we generally do not calculate this difference for everyday activities, and as educational systems across the country follow IST, the time in Gujarat would technically be the same as in Arunachal Pradesh.
So, if it is 7:00 am in Arunachal Pradesh, officially, it would also be 7:00 am in Gujarat as per Indian Standard Time. However, due to natural sunlight, it might still be dark in Gujarat while it's already bright in Arunachal Pradesh at that hour. It's an interesting fact that students can learn about geography's impact on our daily lives!
