Answer:
Time @ 80° East = 6:20pm
Explanation:
Longitude=80°E
Longitude=30°E
longitudinal rule state that = East - East = Subtract
longitudinal difference= 80° - 30° = 50°
Every 15° =1 hour and 1° = 4 minutes
Divide = 50°/15
= 3 hours remainder 5°
since 1° = 4minutes,
Multiply = 4 minutes × 5 = 20 minutes
Therefore, 50° = 3hours 20 minutes
Add , since longitude 80° East is ahead of longitude 30° East = 3:00pm +3:20
= 6:20pm
Therefore @ 80° East = 6:20pm
