Question

If it is 10 p.m. on 21st june at Prime Meridian what will be the date and time on 120 degree east and 160 degree West and 60 degree east

Answer 1

prime meridian - 0 degree
time at prime meridian = 10pm or
22.00 hours
1 longitude = 4 minutes
longitudinal difference = 0 - 120= 120
Time to be added = 120×4 = 480 Mins
480 ÷ 60 =8 hrs
therefore 22+ 8 = 30
30 - 24 = 6
time over there 6.00 am






longitudinal difference = 0-160 = 160
Time to be added = 160×4=640
640÷60 = 1.4 hrs
22.00. 21 .60
1 .04. 1 .04
20. 56
time 20.56 hrs or 8.56 pm




longitudinal difference= 0 -60 = 60
Time to be added = 60 × 4 = 240
240÷60= 4hrs
22+4=26
26-24= 2.00
time - 2 am



hope it helps u
