Question 31

What is the time at New York (74° W) when it is noon at Greenwich?

Answer

The longitudinal difference between New York and Greenwich is: 74°

For 1° longitudinal difference time is 4 minutes.

So, for 74° longitudinal difference the time difference is: 74° x 4 = 296 minutes or 4 hours 56 minutes.

As New York is situated in the west of Greenwich, its local time will be behind the time of Greenwich.

The local time of New York will be: 12 noon - 4 hours 56 minutes = 7:04 am.
