Ha ha, let me give you an analysis:
First of all, when did you start climbing mountains? For example, when, when, every minute! ~
Secondly, it depends on where it is, whether it is extremely day (night). And what is the definition of the sky in the question! Do you think of every day and night as a day, that is, the dawn to the next dawn is the beginning of a day, or do you think of 0: 00 a.m. as the beginning of a day? If the day starts at 0: 00 in the morning, do you still need to know when it will get dark? What time does it dawn? Regardless of winter and summer, we should always consider the international standard time system!
Finally, it depends on whether Comrade Gui has been affected by other factors in this process, such as being hit by a meteor, being taken away by poachers and being struck by lightning! ==
Note: Because the stem indicates the number of days (white/black) that the tortoise crawls, it is considered that its crawling speed is variable in each crawling cycle and constant on the same day! So the crawling distance of each cycle and every white (black) day remains the same!
All right! After analyzing every possible factor, let's look at the results that each possibility will lead to:
Let's start with simple results caused by simple factors:
First, treat every day and night as a day, that is, treat dawn as the beginning of a day until the next dawn. mention
Cann't climb out: turtle personal factors: hung up, fell asleep, ability, =
Force majeure =!
Climb out:
Start climbing at dawn (at this time, dawn time has no effect on the result).
In the non-polar region, if there is no accident, the tortoise will climb out in the dark on the fourth day
The area of extreme days depends on how many days there are, and also depends on the definition of days! Only in this way can we decide!
Start climbing at some time after dawn (at this time, the time of dawn will affect the result:)
To put it simply, in non-polar regions, at the equinox in spring (autumn), or in equatorial regions, the tortoise begins to climb up after dawn 1 s, so that the tortoise is still 3/3600* 12 meters away from the wellhead at the fourth day of darkness. Fall back to 2 meters at night and climb out at dawn on the fifth day!
(The statement is based on the principle of simplicity and practicality. Every day is regarded as 24 hours, and the minimum time unit is seconds. The calculation shows that the error is within 5%, so this assumption can be adopted. )
Make it complicated!
In non-spring (autumn) equinox, equatorial region and non-polar day (night) region, if climbing starts after x seconds after dawn, then the distance from No.4 to the wellhead is X*3/(Y*3600) meters at the moment of darkness. Please check whether this value is greater than 1 (because the next white turtle has to climb 3 meters). If (2+ this number) is greater than 3 meters, if it is greater than 1, please use this method for analogy calculation! Y is the time when the day breaks.
Note: the spring (autumn) equinox, equatorial region and polar region are emphasized because they have an influence on Y!
