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!
