Answer: 16 hours each week.
Step-by-step explanation:
On weekdays, the show is two hours long. There are five weekdays, so 2 x 5 = 10. A total of 10 hours is broadcasted on weekdays. Then, because the show is an hour longer on Saturdays and Sundays, we can do 10 + 3 + 3, where each 3 would represent a Saturday and a Sunday. 10 + 3 + 3 = 16, so a total of 16 hours of the show is broadcasted weekly.
