How many seconds are there in one year

Question

It ask you how many seconds are there in 1 year

Answer 1

Tim C.'s answer is probably what your teacher

expects to see.  However::::

 

This is fine for a calendar year.  For an actual year,
the amount of time it takes for the earth to complete
one revolution around the sun, we must add another
6 hours worth of time.  A true year is 365 days and
6 hours...  This is the reason we have Leap Year every
four years.
(6 hours)(60 mins/hr)(60 sec/min) = 21,600 seconds
 
31536000 + 21,600 = 31,557,600 seconds in a true year.

Answer 2

Let's first calculate how many seconds are in an hour

 

H = 60 x 60 = 3600

 

Then calculate seconds in a day

 

D = 24 X 3600 = 86400

 

Then calculate seconds in a year:

 

Y = 365 x 86400 = 31536000
