Copy and complete each statement.

7 days = ________ $s$

To determine

To fill the blank in given statements:

“ $7\text{ days}=\underset{\_}{}\text{s}$ ”

Answer to Problem 25P

  $7\text{ days}=\underset{\_}{\text{ 604800 }}\text{s}$

Explanation of Solution

Given:

“ $7\text{ days}=\underset{\_}{}\text{s}$ ”

Concept Used:

• One day has 24 hours
• One hour is equals to 60 minutes
• One minute is equals to 60 seconds.

Calculation:

In order to fill the given blank:

“ $7\text{ days}=\underset{\_}{}\text{s}$ ”

First convert given days in minutes. For that calculate number of minutes in one day first.

Since, one day has 24 hours, and each hour has 60 minutes, so the number of minutes in one day can be calculated as:

  $\begin{array}{c}\left(\begin{array}{l}\text{Minutes in}\\ \text{1 day}\end{array}\right)=24\times 60\\ =1440\end{array}$

Now, calculate number of minutes in 7 days

  $\begin{array}{c}\left(\begin{array}{l}\text{Minutes in}\\ \text{7 day}\end{array}\right)=7\times 1440\\ =10080\end{array}$

Now, finally convert these minutes in seconds, since one minute is equals to 60 seconds, i.e. number of seconds in 10080 minutes are calculated as

  $\begin{array}{c}\left(\begin{array}{l}\text{seconds in}\\ 10080\text{ minutes}\end{array}\right)=10080\times 60\\ =604800\text{ seconds}\end{array}$

Thus, the blank in given statement is filled by 604800, as

  $7\text{ days}=\underset{\_}{\text{ 604800 }}\text{s}$
