विकल्प
15 minutes
04 minutes
30 minutes
60 minutes
उत्तर
The differene between the local time of any two consecutive longitudes is 04 minutes.
Explanation:
Longitude is the angular distance of a place east or west of the meridian at Greenwich, England. It is represented in degrees.
One rotation = 360°
The time required for the earth to complete one rotation or 360° = 24 hours
The difference in degrees between any two consecutive longitudes is 1°
thus, the difference between the local time of any two consecutive longitudes = `24/360` hours
= 0.066 hour
1 hour = 60 mins
⇒ 0.066 hour = 4 mins
