.6 of an hour is not 40 minutes, it is 36 minutes. This is worked out by multiplying the decimal and the amount of minutes in an hour.
.6 x 60 = 36 minutes
Example
.5 x 60 = 30 minutes, half of an hour equals half of an hour.
It is 57/60, which can be simplified but, in my view, the unsimplified version is easier to work with.
if you are making 28 dollars an hour and working 40 hours a week, you are earning 1,120 dollars a week. If you work 52 weeks in a year, you will earn 58,240 dollars.
regulary she works 8 times 60=480 minutes but it depends if she comet to work late or gets off early or even she supoosed to work another part time job as well ..
2.75 hours is 2 hours and 45 minutes. So you would leave at 2:15.
if you work eight hours a day five days a week that's 40 hrs. a week times 52 weeks in a year which equals 47,840 dollars
To work this out you need to divide the minutes by 60, as there are 60 minutes in 1 hour. 2505 divided by 60 minutes equals 41.75 hours. Or 41 hours 45 minutes.
2,400 minutes
Your 1.2 hours is 1 hour and 12 minutes, or 72 minutes. You know an hour is 60 minutes, so 0.1 hours is 6 minutes. You can work that in your head. If 0.1 hours is 6 minutes, then 0.2 hours is twice that, or 12 minutes. The 1 hour, the 60 minutes, plus 12 minutes is 72 minutes. You don't need a calculator for this one.
Kelly needs 15 + 20 + 35 = 70 minutes or 1 hour 10 minutes before she goes to work. She has to get up at 7:50. 9 hours 00 minutes - 1 hour 10 minutes or 8 hours 60 minutes -1 hour 10 minutes = 7 hour 50 minutes.
It is: 1/5 of 60 minutes = 12 minutes
To work this out, you first have to convert the hour into minutes so we have consistent units. There are 60 minutes in an hour. So the question can be states as "what fraction of 60 minutes is 10 minutes." This is 10/60. That can then be simplified to 1/6
Kelly needs 15 + 20 + 35 = 70 minutes or 1 hour 10 minutes before she goes to work. She has to get up at 7:50. 9 hours 00 minutes - 1 hour 10 minutes or 8 hours 60 minutes -1 hour 10 minutes = 7 hours 50 minutes.
There are exactly 144,000 seconds in a 40 hour work week. There are 2,400 minutes in 40 hours and 144,000 second in 2,400 minutes.
There are 2160 minutes in 36 hours, since 36 hours * 60 minutes/hour = 2160
0.25 is 25% or a quarter of a whole. On a clock it is 15 minutes, which is a quarter of an hour.
20 minutes to an hour
There are 1440 minutes in a day. 90/1440 = 0.0625 = 6.25%
