What is the time in country A located on 45 degree east ahead if the time at Greenwich is 12 noon?

What is the time in country A located on 45 degree east ahead if the time at Greenwich is 12 noon?

Since the earth turns from west to east once around the equator, 360º, in one day, 24h, you can calculate that it turns 15º in 1h. If you want the local time at 45º East when it is 12:00 noon at Greenwich mean time, you have to calculate the hours from Greenwich, which is 45º/15º gives you 3h.

How do you calculate time using 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).

When you move east by 1 degree longitude the time will?

The prime meridian is also where the system of 24-hour timekeeping that is called Greenwich Mean Time (GMT) originated. As you go east from the prime meridian, the time zones increase consecutively by one hour, or conversely, decrease consecutively by one hour as you go west.

What is the distance between two longitudes?

The distance between longitudes at the equator is the same as latitude, roughly 69 miles. At 45 degrees north or south, the distance between is about 49 miles (79 km). What is this? The distance between longitudes reaches zero at the poles as the lines of meridian converge at that point.

How many longitudes are there in India?

Therefore, the total number of latitudes are 181; and the total number of longitudes are 360.

Where is 45 degrees east longitude?

The meridian 45° east of Greenwich is a line of longitude that extends from the North Pole across the Arctic Ocean, Europe, Asia, Africa, the Indian Ocean, the Southern Ocean, and Antarctica to the South Pole. The 45th meridian east forms a great circle with the 135th meridian west.

What are longitudes and time?

The rate of the time at which the sun traverses over certain degrees of longitudes is used to determine the local time of an area with respect to the time at the Prime Meridian (0°Longitude).

How many hours is a degree of longitude?

15 degrees
Answers: 360 degrees ÷ 24 hours = 15 degrees per hour. Each time zone covers 15 degrees of longitude.

What distance is 1 degree of longitude?

about 111 kilometers
A degree of longitude is about 111 kilometers (69 miles) at its widest. The widest areas of longitude are near the Equator, where the Earth bulges out. Because of the Earth’s curvature, the actual distance of a degrees, minutes, and seconds of longitude depends on its distance from the Equator.

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 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.

Why is 45 East 2 hours ahead of 15 East?

Your two longitudes are 30 degrees apart so they will be two hours apart. With the earth rotating from West to East, this makes the time at 45 East 2 hours ahead of that at 15 degrees East. This works for areas with time zone boundaries running due North/South.

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.
