Answer 2

Answer:

The local time in Chicago is 6:12 AM

Explanation:

Given,

The time in Greenwich is noon and also given Chicago is 87°W from Greenwich

To find,

The local time of Chicago

Solution:

We know that it takes 4 minutes to cross 1° longitude and also when we move West of GMT, the time decreases.

Here, 87° = 87 × 4 = 348minutes =  5 hours 48minutes

Since Chicago is 87°W of Greenwich, the local time in Chicago is 5 hours 48 minutes before GMT

Hence the local time in Chicago is 12 PM - 5 hours 48 minutes

= 6:12 AM

∴ The local time in Chicago is 6:12 AM
