Question

if it is 12 noon at 60 degree east longitude then explain what would be the time at 30° west longitude

Answer 1

I think that it will be 6 in the evening

Answer 2

30° west x 60 = 1800 miles,
So it’s 10:00.

60° east x 60 = 3600 miles,
So it’s 01:00.

15:00 turned back to noon, 3 hours to answer the question.

12:00 and 7:00. Five hours apart.

So it is 7:00 in 30° West longitude.
