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

### Instruction:
Tim decides to do a movie marathon.  The first movie is 2 hours long.  The next movie is 50% longer.  And the last movie is 1 hour shorter than the combined time of the previous 2 movies.  How long was his movie marathon?

### Response:
 Filamu ya pili ilikuwa na muda mrefu wa masaa 2 * 0.5 = 1 zaidi ya filamu ya kwanza.
Hivyo filamu ya pili ilikuwa na muda wa masaa 2 + 1 = 3.
Hii inamaanisha filamu mbili za kwanza zilikuwa na muda wa pamoja wa 3 + 2 = 5 masaa.
Hivyo filamu ya mwisho ilikuwa na muda wa masaa 5 - 1 = 4.
Hii inamaanisha marathon ilidumu kwa masaa 5 + 4 = 9.
