The number of seconds in a 40-hour work week can be calculated as follows:

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!
