take time does one longitude take to pass by the sun.
How many minutes it takes to travel from one longitude to another?
Each degree is divided into minutes and minutes into seconds. 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 does longitude help calculate time?
Explanation: ANS Every gain or loss of 1° longitude stands for 4 minutes. … on
every longitudinal degree increase towards west, substract 4 min
. After the hours is calculated add(if east) or substract( if west) it with time of GMT.
What distance is 1 degree of longitude?
One degree of latitude equals approximately 364,000 feet (69 miles), one minute equals 6,068 feet (1.15 miles), and one-second equals 101 feet. One-degree of longitude equals
288,200 feet (54.6 miles)
, one minute equals 4,800 feet (0.91 mile), and one second equals 80 feet.
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 does the Earth rotate 1 degree of longitude in 4 minutes?
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. Thus, one degree of longitude takes 4 minutes (1 hour = 60 minutes, divided by 15° per hour = 4 minutes
per longitude
).

How long is a longitude?
A degree of longitude is widest at the equator with a distance of 69.172 miles (111.321 kilometers). The distance gradually shrinks to zero as they meet at the poles. At 40 degrees north or south, the distance between a degree of longitude is
53 miles (85 kilometers)
.
How long is a latitude degree?
One degree of latitude, called an arcdegree, covers
about 111 kilometers (69 miles)
. Because of the Earth’s curvature, the farther the circles are from the Equator, the smaller they are. At the North and South Poles, arcdegrees are simply points. Degrees of latitude are divided into 60 minutes.
How do longitudes and latitudes help?
Latitude and longitude make up the grid system that
helps us identify absolute, or exact, locations on the Earth’s surface

360 degrees
of longitude and the longitude line of 0 degree is known as Prime Meridian which passes through Greenwich in England. On one side of the Prime Meridian is the Eastern Hemisphere and on the other is the Western Hemisphere.
What are longitudes called?
Longitudes are known as
meridians
because in Geographical sense, meridians are great circles which are not parallel to each other but intersect each other at the North and the South Poles.
Which is the longest latitude?
The Equator
is the longest circle of latitude and is the only circle of latitude which also is a great circle.
How many longitudes pass the sun in 24 hours?
Answers: 360 degrees ÷ 24 hours =
15 degrees per
hour. Each time zone covers 15 degrees of longitude.
How do you prove 1 degree is 60 minutes?
- Answer: One degree is split into 60 minutes of arc and one minute split into 60 seconds of arc. The use of degrees-minutes-seconds is also recognized as DMS notation.
- To Prove. 1 degree = 60 minutes.
- Proof. We know that. 1 minute = 60 seconds. 1 day =24 h0urs.
How far does the earth rotate in 1 minute?
At the equator, the rotation speed is about 1670 km per hour. You can do the math to convert that to km per minute. It’s
nearly 28 km per minute
.
How many longitudes does the sun pass hourly?
eastern and western hemispheres. In other words, the sun traverses
150
of longitudes per hour or one degree of longitude in every four minutes of time.
What is the 0 degree longitude?
The prime meridian
is the line of 0° longitude, the starting point for measuring distance both east and west around the Earth. The prime meridian is arbitrary, meaning it could be chosen to be anywhere.
How do you convert longitude to hours?
Step two: find your time zone
Here’s how longitude converts into your personal time zone:
15 degrees of longitude = 1 hour difference
; 1 degree longitude = 4 minutes difference. 15 minutes of longitude = 1 minute difference; 1 minute of longitude = 4 seconds difference.
How longitude and time are connected?
It
takes 4 minutes to travel
from one longitude to another. So, generally 1 degree difference in Longitude, causes a difference of 4 minutes. The places located in the East of the Prime Meridian are ahead in time to the places located in the Western Hemisphere.
Why is it 5 30 pm in India when it is 12 noon in London?
This is
because the Earth rotates 360 degrees in 24 hours, 1 degree in 4 minutes
. The standard meridian of India is 82 degree 30E, and that of London is 0 degree. So when it is 12 noon in London, it is 5.30 pm in India.
