How many minutes are there in ten years? - Answers

About 365.25 days are in each year and 366 in a leap year ( to even up that extra .25 that accumulates each year).So There are 1440 minutes in a day. (60x24) Therefore there are 525960 minutes in 1 year (1440x365.25) So in 10 years there are 5259600 minutes. (525960x10) But don't forget to add two leap year days of 1440x2= 2880.So the correct full answer is 5262480. Edit: This is incorrect. If one counts a year as 365.25 days, a leap year should not be included. In the standard calendar year, 365 days exist. The leap year is added every 4th year to account for the fraction of a day that isn't counted. The mistake above is that the leap year is being counted twice. The correct answer is 5,259,600 minutes in 10 years (60 * 24 * 365.25 * 10). Note that this is based on a Julian year.Source: http://www.regenstrief.org/medinformatics/ucumThat is the exact answer, but it depends on how advanced your maths lesson is and how exact you want to be. Very basic version is as follows. 1440 mins in 1 day x 365 = 525600. Gives 1 year in minutes at the basic 365 day year. Multiplied by 10 gives you 5256000 minutes. However there are two leap years in this time with an extra day which gives you an extra 1440 minutes x2. This is 2880. Add this to your total of 5256000 and it gives you 5258880. In conclusion, as you can see there are two very different numbers and different ways of working it out. The first one is the exact correct number, but the second one is probably the right answer in school use since at a basic school level of maths a day is a fixed 365 and is not a second more. Whereas in the real world, it is not.
