First we can calculate how many seconds there are in an hour:​

Since 1 hour has 60 minutes and each minute has 60 seconds.​

Then 1 hour = 60 minutes * 60 seconds/1minute = 3,600 seconds.​

Now we have to multiply x 40 to calculate how many seconds there are in 40 hours.​

In a 40-hour work week = 40 hours * 3,600 seconds/1hour = 144,000 seconds​

Answer : 144,000 seconds there are in a 40-hour work week​

​Hope this helps!

The expression to find the number of seconds in a work week is required.

The required expression is (A) [tex]40\ \text{h}\times \dfrac{60\ \text{min}}{1\ \text{h}}\times \dfrac{60\ \text{s}}{1\ \text{min}}=144000\ \text{s}[/tex]

We need to convert 40 hours to seconds.

[tex]1\ \text{hour}=60\ \text{minutes}[/tex]

[tex]1\ \text{minute}=60\ \text{seconds}[/tex]

[tex]60\ \text{minutes}=60\times 60\ \text{seconds}[/tex]

So,

[tex]1\ \text{hour}=60\ \text{minutes}=60\times 60\ \text{seconds}[/tex]

Now, for 40 hours

[tex]40\ \text{hours}=40\times 60\times 60[/tex]

Hence, the required expression is (A)

[tex]40\ \text{h}\times \dfrac{60\ \text{min}}{1\ \text{h}}\times \dfrac{60\ \text{s}}{1\ \text{min}}=144000\ \text{s}[/tex]
