Since a week is seven days and a day is 24 hours, there are 168 hours in a week. The number of work hours in a week is usually 40. Full-time workers have 8 working hours per day, 5 days per week.
The number of hours in a week is standard. Here are the calculation:
7 days * 24 hours = 168 hours
In 2 weeks we have 14 days. 14 days * 24 hours = 336 hours. Therefore, in 2 weeks we have 336 hours.
For a full time worker, that works 5 days per week, 8 hours per day we have 40 working hours per week.

In one week there are 10080 minutes. Here is the reasoning. One week has 7 days. One day has 24 hours. One hour has 60 minutes. So, by multiplying 7 days with 24 hours and 60 minutes we get 10080, or the number of minutes in a week.
