Question

$\text{State the number of seconds in a day.}$

• A. $\text{36000 seconds}$
• B. $\text{86000 seconds}$
• C. $\text{86400 seconds}$
• D. $\text{24000 seconds}$

Answer 1

The correct option is C

$\text{86400 seconds}$

$\text{1 day = 24 hours}$
$\text{1 hour = 60 minutes}$
$\text{1 minute= 60 seconds}$
$\text{So 1 hour = 60}\times \text{60 = 3600 seconds}$
$\text{1 day = 24}\times \text{3600 = 86400 seconds}$
