# How do you find the distance between two points on the surface of the Earth?

## How do you find the distance between two points on the surface of the Earth?

For this divide the values of longitude and latitude of both the points by 180/pi. The value of pi is 22/7. The value of 180/pi is approximately 57.29577951. If we want to calculate the distance between two places in miles, use the value 3, 963, which is the radius of Earth.

## What is the distance between 2 points is called?

The distance between two points is called the length of the line segment. Segments having the same length are called congruent segments. We can calculate the distance between two points by drawing a line using a ruler.

**What is the distance along the surface of the Earth between two points on the same meridian separated by one degree of latitude?**

110 km

So 1° of longitude at the equator, or 1° of latitude, is about 40,000/360 = 110 km.

**How do you find the distance between two latitudes?**

If you treat the Earth as a sphere with a circumference of 25,000 miles, then one degree of latitude is 25,000/360 = 69.44 miles. A minute is thus 69.44/60 = 1.157 miles, and a second is 1.15/60 = 0.0193 miles, or about 101 feet.

### Can the distance between two points be zero?

If two points are coincident (same), then the distance between them is said to be zero.

### How many km is between latitudes?

approximately 111 km

The degrees of latitude are parallel, so the distance between each degree remains same. It is noteworthy that Earth is not spherical but slightly elliptical in shapes which cause small variation between the degrees. 1. The distance of each degree of latitude is approximately 111 km.

**What is the distance between latitude and longitude lines?**

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 each latitude?**

69 miles

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.

## What is the distance of 1 second of latitude?

about 90 feet

There are 60 seconds to a minute, so 1 second of latitude is 1/60 mile or 5280/60 feet. That comes to about 90 feet. The distance corresponding to a second of longitude will depend on where you are. If you are at the equator, a circle of longitude is still the same 24,000 miles, so 1 second is again about 90 feet.

## Is negative distance possible?

The distance can never be zero or negative. Distance will not decrease. Distance is a scalar quantity which has only magnitude.

**Why is distance never zero?**

Displacement can be zero but distance cannot be zero because distance is the total path covered but displacement is the shortst distance between the initial and final position. It can be zero at the end of one round. if dist. 0 then there no displacement.

**What distance is 1 degree of longitude?**

54.6 miles

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.

### How many miles around the Earth in a straight line?

24,901 miles

The distance around the Earth at the Equator, its circumference, is 40,075 kilometers (24,901 miles).

### How far is 1 degree of longitude at the equator?

60 geographical miles

A geographical mile is defined to be the length of one minute of arc along the equator (one equatorial minute of longitude) therefore a degree of longitude along the equator is exactly 60 geographical miles or 111.3 kilometers, as there are 60 minutes in a degree.

**How far is an arcsecond on earth?**

At the equator, an arc-second of longitude approximately equals an arc-second of latitude, which is 1/60th of a nautical mile (or 101.27 feet or 30.87 meters).

**Can the distance be zero?**

Yes. The distance can be zero when the object is at rest. Distance is a measurement of how far apart objects are. It can also be defined as the length of the path between any two points.

## Is displacement can be zero?

Displacement can be zero even when distance is not zero. Consider two points A and B such that AB = 5 m. When a car travels from A to B and then back from B to A, distance = 5+5 = 10 m. Displacement = Minimum distance between final(B) and initial position(B) = 0.

## Is speed can be zero?

Speed is the distance travelled in the given time. Distance can never be zero. Therefore, average speed will always be a positive value and will not be zero.

**Is distance ever negative?**
