Early versions erred by less than one minute per day, and later ones only by 10 seconds, very accurate for their time. Dials that showed minutes and seconds became common after the increase in accuracy made possible by the pendulum clock. Brahe used clocks with minutes and seconds to observe stellar positions. [112]
The day is divided into 10 16 (16 10) hexadecimal hours, each hour into 100 16 (256 10) hexadecimal minutes, and each minute into 10 16 (16 10) hexadecimal seconds. History [ edit ]
Some formats include a lightning round during which a team attempts to answer multiple questions as fast as possible under a given time limit, usually sixty seconds. Other formats include a written worksheet round, where teams work together for 2–5 minutes to agree on their written answers. [20] [21] [22]
Minute is a unit of time defined as equal to 60 seconds. [1] One hour contains 60 minutes. [2] Although not a unit in the International System of Units (SI), the minute is accepted for use in the SI. [1] The SI symbol for minutes is min (without a dot). The prime symbol ′ is also sometimes used informally to denote minutes. [3]
