Q.2 Estimate your age in minutes and seconds.

Ans: Suppose my age = 15 years
= 15 x 365 = 5475 days        (1 year = 365 days)
= 5475 x 24 = 131400 hours    (1 day = 24 Hours)
= 131400 x 60 = 7884000 minutes  (1 hour = 60 Minutes)
= 7884000 x 60 = 473040000 seconds    (1 minute = 60 second)

Therefore, if I am 15 years old, my age in minutes is approximately
7,884,000 minutes, and in seconds, it’s about 473,040,000 seconds
