So, how much is 3 minutes in an hour?
First Step: realize there are 60 minutes in 1 hour. Second: take the total number of minutes, in this case it's 180 and divide by number of minutes in an hour, in this case it's 60. Result: 180 / 60 = 3. You're done!
What is 2.5 of an hour?
Usually a decimal portion of an hour is followed by "hours". Like 2.5 hours, 1.5 hours, 0.5 hours etc. However normally we say half an hour or thirty minutes not 0.5 hrs.

How longitudes are used to calculate time?
Because one day is 24 hours long one can easily use time to calculate longitude. One hour of time difference corresponds to 15° of longitude (360°/24 hours = 15°/hour). Suppose an observer sets his accurate watch to 12:00 at noon in Greenwich, England and then travels a great distance.

How do you add and subtract time?
Follow these steps:
- Subtract the hours.
- Subtract the minutes.
- If the minutes are negative, add 60 to the minutes and subtract 1 from hours.

What time is it in the different time zones?
Standard time and daylight saving time
| Time Zone | Standard Time | Daylight Time |
|---|---|---|
| Alaska Time Zone | AKST (UTC−09:00) | AKDT (UTC−08:00) |
| Pacific Time Zone | PST (UTC−08:00) | PDT (UTC−07:00) |
| Mountain Time Zone | MST (UTC−07:00) | MDT (UTC−06:00) |
| Central Time Zone | CST (UTC−06:00) | CDT (UTC−05:00) |

What was the first country to adopt time zones?
On November 2, 1868, the then-British colony of New Zealand officially adopted a standard time to be observed throughout the colony, and was perhaps the first country to do so. It was based on the longitude 172°30′ East of Greenwich, that is 11 hours 30 minutes ahead of GMT.

Why do we have different time zones around the world?
If we had one single time zone for Earth, noon would be the middle of the day in some places, but it would be morning, evening, and the middle of the night in others. Since different parts of Earth enter and exit daylight at different times, we need different time zones. Each time zone is 15 degrees of longitude wide.

How many latitudes are there on the earth?
Everything north of the equator is known as the Northern Hemisphere and everything south of the equator is known as the Southern Hemisphere. Lines of latitude are called parallels and in total there are 180 degrees of latitude. The distance between each degree of latitude is about 69 miles (110 kilometers).
9
How many lines of longitude are there in the world?
The primary unit in which longitude and latitude are given is degrees (°). There are 360° of longitude (180° E ↔ 180° W) and 180° of latitude (90° N ↔ 90° S). Each degree can be broken into 60 minutes ('). Each minute can be divided into 60 seconds (”).
10
What do you mean by time zone?
A time zone is a region of the globe that observes a uniform standard time for legal, commercial, and social purposes. Time zones tend to follow the boundaries of countries and their subdivisions because it is convenient for areas in close commercial or other communication to keep the same time.
11
Why is there an international date line?
The International Date Line, established in 1884, passes through the mid-Pacific Ocean and roughly follows a 180 degrees longitude north-south line on the Earth. It is located halfway round the world from the prime meridian—the zero degrees longitude established in Greenwich, England, in 1852.
12
What is the distance between two longitude?
Degrees of latitude are parallel so the distance between each degree remains almost constant but since degrees of longitude are farthest apart at the equator and converge at the poles, their distance varies greatly. Each degree of latitude is approximately 69 miles (111 kilometers) apart.
13
What is the relationship between the longitude and time?
Longitudes run from North to South,from 0 degrees(which passes through Greenwich(England) and sometimes called the Greenwich Meridian)to 180 degrees East or West. Generally 1 degree difference in Longitude, causes a difference of 4 minutes,with the longitude East always ahead in time.
14
What is the difference between the prime meridian and the equator?
The Equator separates the Northern and Southern Hemispheres. The Equator is at 0° latitude. The Prime Meridian separates the Eastern and Western Hemispheres. The Prime Meridian runs through Greenwich, England and is at 0° longitude.
15
Which Latitude correspond to North and South Pole?
The Equator is the line of 0 degrees latitude. Each parallel measures one degree north or south of the Equator, with 90 degrees north of the Equator and 90 degrees south of the Equator. The latitude of the North Pole is 90 degrees N, and the latitude of the South Pole is 90 degrees S.
16
What are the five major lines of latitude?
The five major circles of latitude are, from north to south:
- The Arctic Circle (66°N)
- The Tropic of Cancer (23° N)
- The Equator (0° latitude)
- The Tropic of Capricorn (23°S)
- The Antarctic Circle (66°S)
17
Which is the largest latitude?
Longitude is in the range -180 and +180 specifying coordinates west and east of the Prime Meridian, respectively. For reference, the Equator has a latitude of 0°, the North pole has a latitude of 90° north (written 90° N or +90°), and the South pole has a latitude of -90°.
18
What is the longest line of latitude on the earth?
On a globe of the Earth, lines of latitude are circles of different size. The longest is the equator, whose latitude is zero, while at the poles--at latitudes 90° north and 90° south (or -90°) the circles shrink to a point.
19
How many latitudes are there in total?
Everything north of the equator is known as the Northern Hemisphere and everything south of the equator is known as the Southern Hemisphere. Lines of latitude are called parallels and in total there are 180 degrees of latitude. The distance between each degree of latitude is about 69 miles (110 kilometers).
