A can do a particular work in 6 hours and B can do the same in 14 hours. How much time will it take if they do the work together?
In 6 hours A can do a workso, in 1 hour A is doing 1/6 of the work . similarly B is doing 1/14 of the work in 1 hour .they together in 1 hour are doing (1/6+1/14) of the work .=(7+3)/42 =10/42=5/21 of the workso, together they will complete the work in 21/5 days =4.2 days
If a person sleeps 8 hours a day, how many months do they spend sleeping in a year?

If the earth rotates at 23 hours and 56 minutes and 4 seconds how long is a year? And what year would it be if we didn't follow the 24 hour rounding?
There are actually two kinds of days.The one that we are most familiar with is technically a solar day. A solar day is exactly 24 hours. It is defined as the amount of time it takes for the Earth to make one full rotation with respect to the Sun - that is to say, there is exactly 1 solar day (and therefore 24 hours) in the time required for the Sun to return to its same position in the sky.What you are referring to is knowns as a sidereal day. The sidereal day is 23 hours, 56 minutes and 4.0916 seconds long. It is defined as the amount of time it takes for the Earth to make one full rotation with respect to the stars - that is to say, there is exactly one sidereal day in the time required for a given star to return to its same position in the sky.The reason for this discrepancy is that the Earth orbits the Sun and after one full rotation, the Sun no longer occupies the same spot in the sky. In our everyday lives we tell time based on the solar day to keep the Sun in sync with our clocks. If we did not, sunrise would drift through the hours such that sometimes it would rise at 6am, sometimes at 12 noon, sometimes at 6pm and sometimes at 12 midnight. For obvious reasons this does not work, and we define our days based on the Sun rather than the time it takes the Earth to rotate once.So, there is no rounding up to 24 hours. A solar day is exactly 24 hours, but it is not one full rotation of the Earth.A calendar year is 365.2425 solar days long. Things get complicated when you realize there are more than one kind of year, as well, but I won't go into that in this answer.
How many days does the average person lose watching commercials in a lifetime?
Great question! Let's do the math...The average American watches four hours of TV each day (that's down from about six hours in the 1960s through 1990s by the way). There are about twenty minutes of "non-program material" per hour, which includes ads, promos, news updates, etc. For our purposes, let's consider all of this commercial matter. So in four hours, we see eighty minutes of commercials.In the course of a year that makes 29,200 minutes of commercials. Divided by 60 minutes per hour, that's 487 hours of commercials perr year, or a bit over twenty days.Let's assume the average person begins watching TV at age three and continue through age eighty. That's 77 years times 20 days per year for a total of 1,540 days. We divide that by 365 days per year... and end up watching 4.2 years of commercials over the course of our lives.That's not as much as I thought it might be. But still, wow!
What is the average amount of work days in a month?
Pat Harkin has the math correct to get an average of 21.74 if you ignore holidays and vacation. I will just add the 10 US Federal Holidays and typical vacation benefits to the equation and show the detailed math:Note that these calculations determine averages. Depending upon how the weekends fall in any given year - and whether the year is a Leap Year or not - the actual number of work days per year or per month will vary. That’s why the averages are not whole numbers.Edit: corrected a label and added calculations for 3, 4, and 5 weeks of vacation.
If 3 men completes work in 7 days how many days will 5 men take?
Hi,Here is an easy solution of your question.If 3 man can complete the work in 7, days then 1 man will complete the work in 7×3=21 daysThen5 man will complete the work in 21÷5= 4.2 days.
How long would it take to travel a light year at 60 miles per hour?
First we need to find out the distance light travels in a year: 186,223 miles/sec •365 days/yr. •24hrs/day•60 min/hr• 60sec/min which is the same thing as saying the distance light would travel in the total number of seconds that one year has, which from the above calculation works out to be 5,872,728,528,000 miles(in the order of nearly 5.9 trillion miles). Now we must divide this number by 60 miles per hour to get the number of hours needed which works out to: 97,878,808,800 hours(In the order of 97.9 billion hours). Now to convert this to days, must divide by 24, which gives 4,078,283,700 days,(in the order of 4 billion days), which we will further divide by 365, which gives 11,173,380 years!!!( in the order of 11 million earth years that it will take to traverse the distance that light crosses in a year, if we go at 60 miles per hour, a modest speed on our earth highyways!
