The division of day and night began with the Babylonians and Egyptians, who divided the day and night into 12 equal parts, probably to coincide with the movements of constellations (or the observed number of lunar cycles per year). Because day and night are only equally long at the equator, this would create hours of unequal length. So the 24 hour system, with varying times for sunrise and sunset, was eventually adopted.
The Greeks divided the year into 12 months, to coincide with the 12 observed lunar cycles in a calendar year.
Here is how to find the answer in mathematical steps: We first have to find out how many earth hours 355 Martian days is. Since a Martian day (called a sol) is 24.6 hrs long, we have to multiply 355 sols by 24.6 hrs to get the result of the number of earth hrs in 355 sols. 355 X 24.6 = 8,733.0 earth hours in a sol Next, we have to divide 8,733 hrs by 24 hrs to get the result of how many earth days 8,733 hrs is equivalent to. 8,733 / 24 = 363.875 earth days Finally, we should convert the .875 of 365.875 earth days to hrs. To do this, we have to multiply 24 by .875 24 X .875 = 21 hrs So in conclusion, we find that 355 sols is equivalent to 363 earth days and 21 hrs.
356. There are about 0.975 Martian days in one Earth day, and 365.25 Earth days in one Earth year, and 0.975 * 365.25 ≈ 356.009.
NO!
The axis makes the Earth to rotate. P.S. The Earth takes 24 hours to make a complete rotation on its axis. 2nd answer: More correctly, the Earth orbits the Sun once per year.
Mars takes approximately 24.6 hours to complete one full rotation on its axis, which is very close to Earth's 24-hour day.
about 24 hrs and 1 year
24 hours is 1440 minutes
24 HRS
February has 28 days because when the earth orbit the sun it take 1 year + 6 hrs so, the scientist decided to add these 6 hrs+ 6 hrs+ 6 hrs+ 6 hrs= 24 hrs = 1 day
One Earth Day passes.
We travel about 1670.45 kms per hour relative to the space. Earth takes full circle in 24 hrs. So total distance covered in 24 hrs by any body present on the surface of the earth is equal to the circumference of the earth, which is 2*pi*r where "r" the radius of earth is 6378.1 kms.
It would be more scientific to say "How long is seven sols (Martian days)?" instead of "How long is one week on Mars?" Anyway, let's do this calculation in simple mathematical steps: We first have to find out how many hours 7 sols is equivalent to. We know that a sol is 24.6 hrs (24 hrs and 39 mins) long, so we have to multiply 24.6 by 7 to see how many hrs 7 sols is equal to. 24.6 X 7 = 172.2 hrs So we have found out that 7 sols (one Martian week) is equal to 172.2 hrs. Now, we have to convert 172.2 hrs to earth days by dividing 172.2 hrs by 24 hrs (the length of an Earth day). 172.2 / 24 = 7.175 Earth days Finally, we have to convert the .175 days to hrs and mins. We do this by multiplying .175 by 24 to convert into hrs and then multiplying the decimal part of the result by 60 to also get the mins. .175 X 24 = 4.2 hrs .2 X 60 = 12 mins So in conclusion, we have found that one Martian week (7 Martian days) is equivalent to 7 Earth days, 4 hrs, and 12 mins, which is 4 hrs and 12 mins longer than an Earth week (seven Earth days).

I understand that it takes one full day or 24 hrs. for the earth to complete rotation, and each 12 hrs. the earth has completed half a turn.
24 hours
test divide on Standard multiply to 100 then multiply to volume of 24 hrs urine per deciliter it equal to ( protein ? mg/ 24 hrs urine)
There are 24 hours in one day. Threfore, 424.2 hours is equal to 424.2/24 = 17.675 days.
