You can avoid reality, but you cannot avoid the consequences of avoiding reality.

Since 24hrs = 1day
?? = 365days
24×365 = 8760 hours
convert to seconds
Since 60secs =1min
And mins 60mins = 1hr
8760×60×60 = 31536000 seconds

1 day = 24hour
1hour = 60 minutes
1minutes = 60 seconds

Now,
1hour = 60mins x 60sec
= 3600seconds

1 day = 24 x 3600sec
= 86, 400sec

For 365days
1 year = 365 x 86 400sec
= 31 536 000secs Answer
