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?
Don’t let change and uncertainty hold you back.
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 69°E 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.
