Ayear has 365 days, and a day has 24 hours. if an hour has 60 minutes and a minute has 60 seconds, how many seconds are there in 1 year?

Ok, so we need to take 60 x 60.  That gives us 3600, which is the amount of seconds in 60 minutes.  Then we need to take 3600 x 24, to figure out the number of seconds in 24 hours (1 full day).  That gives us 86,400.  Finally, we take 86400 x 365, to determine how many seconds are in 1 full year (365 days).  That gives us the answer of 31536000.  Hope this helps!
