120 minutes, I think.
As there are 60 minutes in a single degree, 20 minutes contains 1/3 of a degree.
It is instantaneous. A longitude is an idealised line and so infinitesimally thin. To go from one longitude to the next takes approx 15 minutes.
45 minutes is 2,700 seconds.
One degree of longitude is approximately 69 miles (111 km) length at the equator.The distance between lines of longitude, however, gets smaller as you move towards the poles (North or South) since all the lines converge there.
A degree Celsius is equal to 9/5 of a degree Fahrenheit.
10 degree Celsius = 50 degree Fahrenheit.
8.3 Celsius.
The lines don't need to be subdivided. The units of latitude and longitude do,because the degree is a large unit on the Earth's surface. Since latitude andlongitude are angles, you need smaller angle units, to be able to indicate smallfractions of degrees.You can use degrees, minutes, and seconds, if you have an emotional need topunish yourself, or you can use the much simpler decimal degrees. It's easy toconvert the numbers from one system to the other; that's just arithmetic.
