Answer 1

Answer:

Explanation:

Places. Time Longitude

Delhi. 8:30pm. 77°E

Chicago. ? 88°W

Longitude difference= 77°+88°

=165°

Note: we add the longitude when they are on different side of the prime meridian

But 15°= 1 hour

Therefore, Time = 165°/15°×1hour

=11hours

Since Chicago is west of New Delhi we subtract 11 hours from the time of New Delhi

Chicago Time= 8:30pm-11hours

= 9:30am
