Answer 2

Answer:

315 360 000 seconds.

Explanation:

We have 10 years, each one of them has 365 days. Every day consists of 24 hours. Hour has 60 minutes and every minute is just 60 seconds.

To answer this question we should multiply (number of years)×(number of days each year)×(number of hours each day)×(number of minutes each hour)×(number of seconds each minute):

10×365×24×60×60 = 315 360 000 seconds.
