Question

If the standard time of Alexandria (30E) Monday morning 6 ‘0’ clock , what will be standard time of new orelans (90w) of USA?​

Answer 1

Answer:

The 120º longitude difference is  13  the circumference of Earth. Since  13  of 24 hours is 8 hours, it “should be” 10 p.m. on the previous day in New Orleans.

However, governments don’t use strict geographic time zones. In the case of Alexandria and New Orleans, the 8 hour difference happens to be accurate between the first Sunday in November and the second Sunday in March.

That’s probably why the writer of the question chose those two cities. Kashgar and São Luís are also 120º apart, and São Luís is 11 hours behind. Apia and Pago Pago are 1º apart and Apia is 25 hours ahead.
