What is the longitude of a place where the local time is 6 am when it is 9 pm at 77 E?

The time difference between the required place and New Delhi is 6 + 9 = 15 hours, so the time in minutes =15 × 60 = 900 minutes So the longitudinal difference = 900/4 = 225°. So the place will be in the west at 225° – 77° = 148° W.

How do you calculate time difference with longitude?

The Earth takes 24 hours to complete one rotation or to cover 360° of longitudes. This means that the Earth covers 15° of longitudes every hour. One degree of longitude takes 4 minutes (1 hour = 60 minutes, divided by 15° per hour = 4 minutes per longitude).

How do you calculate meridian time?

LSTM = The local standard time meridian, measured in degrees, which runs through the center of each time zone. It can be calculated by multiplying the differences in hours from Greenwich Mean Time by 15 degrees per hour. Positive = East, and negative = West.

What is the local time in Singapore 104 E when it is 6’00 pm at Greenwich?

The longitudinal difference in Singapore and Greenwich is 104°, so the time difference is 104 × 4 = 416 minutes i.e. 6 hours 56 minutes. So the time in Singapore will be 12.56 a.m.

What are longitudes Class 9?

Answer: A longitude is the angular distance of a place east or we§t of the Prime Meridian or 0° longitude. The lines of longitude are the great semi-circles joining North pole and South pole and are equal in length. These are 0° – 180°E and 0° – 180°W longitudes or total 360°.

What is the local time at Singapore when it is 6pm at Greenwich?

It is given that the time is 6:00 pm in Greenwich, as Singapore is 6 hours and 56 minutes ahead of GT, local time in Singapore will be 12:56 AM.

What time is it at 90 degrees west longitude on Sunday?

It is 12:00 AM on Sunday at 90 degrees west longitude. What time is it at 180 degrees east? 12 am is 0000 at 90 west.

What is the time at 2° east longitude?

We know that between any two longitudes, there is a time difference of 4 minutes. Therefore, time at 2° East longitude will be 4minutes x 2 = 8 minutes. 2° lies to the right (east) of 0°, so you will add 8 minutes to the given time. Your answer will be 7:08 a.m.

What is the time difference between 10 degrees east and 50 degrees?

Between 10° to 50°, there are total 50-10=40 longitudes. We know that between any two longitudes, there is a time difference of 4 minutes. Therefore, time at 10° East longitude will be 4minutes x 40 = 160 minutes, which is equal to 2 Hrs. and 40 minutes.

What is the time difference between 0° and 82° east?

Between 0° to 82° 30″ East., there will be total 0 + 82° 30″ = 82° and half longitudes. We know that between any two longitudes, there is a time difference of 4 minutes. Therefore, time at 82° 30″ East longitude will be 4 minutes x 82 = 328 minutes + 2 minutes for half degree extra, which is equal to 330 minutes.
