Why is the tidal cycle 24 hours and 50 minutes?
I didn't know that, but it makes sense . . .
The moon is revolving around the earth. Wherever you see it tonight, by the time you rotate
back to the same position 24 hours later, the moon has moved in its orbit, and you have to
keep rotating for another 52.7 minutes to catch up to where it is now.
The time required for the moon to be directly over (or directly south of, or any specific direction from)
the same spot on earth twice is 24hours and 52.7minutes.
Although complex, the tidal cycle is fundamentally related to the moon's daily cycle, so it makes sense
that the tidal cycle should also average out to 24hours 52.7minutes .
660 minutes is how many hours?
Each hour has 60 minutes so 660 minutes divided by 60 minutes = 11 hours.
So 660 minutes is 11 hours
What does 8 hours 23 minutes - 2 hour 45 minutes equals?
8 hours 23 minutes - 2 hour 45 minutes = 5 hours 38 minutes.
What is 15 years if 10 is a decade?
1.5 decades (15 years does not have a specific name for that period of time.)
