1 week = 7 days
1 day = 24 hours
1 hour = 60 minutes
so, 7 x 24
168 hours in one week168 x 60
10080 minutes in one weekto get seconds, multiply by another 60 (1 minute = 60 seconds)
10080 x 60
604800 seconds in one weekfor those wondering about minutes in a day
24 x 60
1440 minutes in one daySo, there would be
1440 x 60
86400 seconds in a day60 minutes = 1 hour
therefore
350 minutes = 5 hours 50 minutes
How many miles a day on average is 4 days?
Not enough information. If you also have the TOTAL number of miles, you can divide that by the 4 days, to get the average miles per day.
How many minutes are in 100 days?
60 minutes = 1 hour
24 hours = 1 day, so
60 x 24 minutes in 1 day = 1440 minutes, then x 100 days = 144000 minutes.
It's neither 12AM nor 12PM. Those are improper terms.
The abbreviations AM and PM stand for Ante Meridiem and Post Meridiem, respectively. The terms ante and post mean before and after. The term meridiem refers to when the sun is at the middle of its arc across the sky.
Nominally the sun is at its meridiem at noon. Since it is *at* its meridiem this is neither before nor after the meridiem. It *is* the meridiem.
Likewise, midnight is neither 12 AM nor 12 PM. It is equally far from both. It is simply 12 midnight.
The military clock is better than the civilian clock for many reasons. One is that eliminates the complexity of specifically accounting for whether a time is before of after midnight. On the military clock noon is read as 1200 hours, and midnight is read as 2400 hours.
Why do you have 60 mins in a hour?
The Babylonians thought it was a good idea. Helped by the fact that 60 is divisible by several small integers so that it is easy to work out a quarter of an hour or a fifth.
Around 1400 BC (around 3,400 years ago), the Egyptians invented the water clock, or as they called it the Clepsydra (pronounced KLEP-suh-druh). These water clocks were made from two containers of water, one higher than the other. The water then travelled from the higher container to the lower container through a connecting tube. The containers had markings on them to show the level of the water and these marks told the time. The idea of a water clock caught on and became very popular, not only in Egypt, but as far as Greece. The design was improved upon over the years and adapted to become easier to use and more accurate. One of the more notable changes was the addition of a floatation device. As the water dripped from the higher container to the lower container, the level of water rose and with it went the float. This float was connected to a stick with notches that, as it moved higher and higher, moved a hand around a clock face. Water clocks were far more popular than sundials for two important reasons. First, unlike the sundial, the water clock did not depend on cloud cover and could even work during the night. This meant that the time could be at hand no matter what the light level. The second reason why people preferred this new way of telling the time is that water clock were far more accurate than the traditional sundial. However, this was still not accurate enough for the Greeks, who when on to develop, days, weeks, months and years, making it a lot easier to keep track of time. This again caught on and we still use it today, but the next really big change in the way people tell the time did not come about for nearly 3000 years.
