Answer 1

Answer:

1o longitude has a difference of 4 minutes. So, 74o longitude will have a difference of 4 hours 56 minutes. Since New York is to the west of Greenwich, subtract 4 hrs 56 minutes from 12 hrs.

Explanation:

Greenwich is 4 hours ahead of New York, NY, USA. Greenwich mean time (GMT) = 12 noon every 1° is equal to 4 minutes. therefore, 74° = 74×4 = 296 minutes.
