Answer» Answer: Explanation: If it is 12 noon at Greenwich, calculate the local time of the places located on the FOLLOWING longitudes: 69°E, 30°W and 12°E? 43 Answers Vinay Sheel Verma Vinay Sheel Verma, CLEARED UPSC CSE mains 2018 Updated Mar 9, 2018 every 1° is equal to 4 minutes. If it is on west of greenwich median than substract the calculated time from actual time of GMT and if it is on east than add. 69°E = 69×4 = 276 minutes i.e 4 hours 36 minutes. time on greewich is 12:00 . so, time on 69°E is 12 +4 hr 36 min = 16:36 similarly in CASE of 30°west we have to substract the time i.e 12 - 2 hrs = 10:00 and for 12°E again add 12+48 min = 12:48 Hope this was helpful. Thanks for A2A P.S Time I followed here is military time i.e 24 hours clock. East or west of longitudes measures from 0° i.e greenwich median line. |
