The ZT at Place A is 0800. If the longitude of A is 49° 30' W, what is the ZT of Place B in longitude 83° 15' W?
Given:
Longitude of Place A = 49° 30' W
Longitude of Place B = 83° 15' W
ZT at Place A = 0800
Find:
ZT of Place B
Solution:
1. Divide the longitude of Place A and Place B by 15. By doing this, we are converting it to ZD.
Longitude of Place A = 49° 30' W ÷ 15 = 3° 18'. The minutes is less than 30, therefore the ZD would be +3.
Longitude of Place B = 83° 15' W ÷ 15 = 5° 33'. The minutes is more than 30, therefore the ZD would be +6.
2. Next is to subtract the ZD of places A and B to get the time difference.
ZD of Place B = +6
ZD of Place B = - +3
Time difference = 3
4. We can solve now for the ZT of Place B.
ZT of Place A = 0800
Time Difference = - 3 (subtract since Place B is located west of A)
0500 is the ZT of Place B

Good pm/am sir!Sir di naba mag chi-change yung +3 if less than 30 tapos +6 naman kung more than 30?
ReplyDeleteTingnan natin yong resulta sa pagdivide. 3 deg 18 mins. Since the minutes is 18 which is less than 30, therefor the ZD is 3.
DeleteIf more than 30 mins like the example which is 5 deg 33 mins, so the author converts it to 6.
Good afternon paano po malaman na sa west po ung place B po sir?
ReplyDeleteTingnan mo ang longitude.
Deletelongitude of A is 49° 30' W. And the longitude of B is 83° 15' W.
Therefore, B is located west of A.
