Question

Express 12 hours in seconds leaving your answer in the standard form.

Answer 1

Step-by-step explanation:

We know that

1 day = 24 hours

1 hour = 60 minutes

1 minute = 60 seconds

So, 1 day = 24 * 60 * 60 seconds

=> 1 day = 86400 seconds

Now, 1 year or 365 days = 365 * 86400 = seconds

= 31536000 seconds

= 3.15 * 107 seconds

Now, 3 years = 3 * 3.15 * 107

= 9.46 * 107 seconds
