2/1

THE ANSWER IS 2:1

Answer 2

Time has been defined as a continuum in which events take place in succession from the past to the present and on to the future. Time has also been defined as a one-dimensional quantity used to sequence events, to quantify the duration of events and the intervals between them, and (used with other quantities such as space) to quantify and measure the movements of objects and other changes.

Day

Definition: A day (symbol: d) is an accepted non-SI unit of time that is defined based on the SI (International System of Units) unit of time, the second, and is equal to 86,400 seconds.

History/Origin: The term "day" comes from the Old English "dæg." It is approximately equal to the period required for the Earth to complete a complete rotation relative to the Sun. It was later redefined in terms of the second in 1960, when the second was redefined in terms of the Earth's orbital motion in 1900. The second, and therefore the day, was redefined in 1967 by the transition of atomic electrons.

Contemporary usage: A day is a term used around the world in many contexts, one of the most common of which refers to a time interval of 24 hours. It is also used to refer to the time of day or period of time during which the sun is above the horizon. The term also has other colloquial uses, such as the day of the week and fixed time periods such as 6:00 a.m. to 6:00 p.m., among others.

Hour

Definition: An hour (symbol: h) is a unit of time commonly defined as 1/24 of a day and 3,600 seconds. In Coordinated Universal Time, a negative or positive leap second may be incorporated to keep the hour within 0.9 seconds of Universal Time, so in some cases the hour is 3,599 or 3,601 seconds.

History/Origin: The term "hour" is derived from the Anglo-Norman "hour" which was used around the 13th century.

There have been many definitions of an hour throughout history based on culture or region, such as an hour being divided into 1/12 periods of daylight or darkness. It is believed that the custom of dividing the cycle of day and night into 24 periods began with the ancient Egyptians.

Current usage: The hour is used globally as a unit of time. Most forms of employment require a certain number of hours worked per day, with compensation based on measured or expected hours worked. Durations from 30 minutes (half an hour) are commonly used colloquially.

To convert daily measurements to hourly measurements, multiply the time by the conversion ratio

Since one day is equal to 24 hours, you can use this simple formula to convert:

hours = days × 24

The time in hours is equal to the number of days multiplied by 24.

$1 day=24 hours\\24*3=72\\72:36\\2:1$
