Question

When time at 90°W is 1500 hrs, the time is 10pm at another place. What is the longitude of the second station

Answer 1

Answer:

difference in time is 7 hours ( 3 p.m. to 10 p.m.)

now 4 min = 1 degree

7 × 60 = 420 min

420 min = 1 / 4 × 420 = 105 degree

90 + 105 = 195 degrees

195 - 180 = 15 degree east
