Answer 1

There is a time lag of two hours from Gujarat to Arunachal Pradesh because of the longitudinal extent of India. Gujarat is situated in the extreme west of India Arunachal Pradesh is situated in the extreme east of India. The Sun rises two hours earlier in Arunachal Pradesh than Gujarat.

Answer 2

Explanation:

As we know that the the sun takes 4 minutes to cross 1 longitude and there is difference of 30 longitudes between Arunachal Pradesh and Gujarat. So,

→ (30 × 4) minutes = Time lag between Arunachal Pradesh and Gujarat

→ 120 minutes = Time lag between Arunachal Pradesh and Gujarat

• 60 minutes = 1 hour, so
• 120 minutes = 2 hours

→ 2 hours = Time lag between Arunachal Pradesh and Gujarat

Considering this, clearly that's the reason the sun rises two hours earlier in Arunachal Pradesh as compared to Gujrat.
