Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
A movie that's 1.5 hours long is being replayed 6 times in one movie theater each day. There is a 20-minute advertisement before the start of the movie. How long, in hours, does the movie theater operate each day?

### Response:
 Filamu ya masaa 1.5 inarudishwa mara 6 kwa siku, hivyo ni masaa 1.5 x 6 = <<1.5*6=9>>9 ya filamu.
Kwa kuongeza matangazo ya dakika 20 kabla ya kila kuonyesha filamu, sinema inafanya kazi kwa masaa 9 + 20 = 11 kila siku.
