Question

Calculate the time: If it is 2.00 pan al 8 E longitude. What will be th time at 77" E loagitude?​

Answer 1

Answer:

If it is 12 noon at Greenwich, calculate the local time of the places located on the following longitudes: 74°W, 105°E, 120°W?

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.

74°W = 74×4 = 296 minutes i.e 4 hours 56 minutes.

time on greewich is 12:00 . so, time on 74°W is

12 - 4 hr 56 min = 7:04

similarly in case of 105°E we have to add the time i.e

105 ×4min = 420 min i.e 7 hours

12 +7 hrs = 19:00

and for 120°W again

120×4 min = 480 min i.e 8 hours

12- 8 hours = 04:00

P.S

Time I have followed is military time i.e 24 hours clock.

East or west of longitudes measures from 0° i.e greenwich median line.

Hope this was helpful.
