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

### Instruction:
Joseph and his friends watched two movies in his house. The first movie is 1 hour and 30 minutes long while the second movie is 30 minutes longer than the first. Before the movies, they spent 10 minutes making popcorn and twice as long making fries. How long, in hours, did it take Joseph and his friends to cook and watch the movies?

### Response:
 Filamu ya kwanza ina muda wa dakika 60 + 30 = <<60+30=90>>90.
Filamu ya pili ina muda wa dakika 90 + 30 = <<90+30=120>>120.
Walitumia dakika 2 x 10 = <<2*10=20>>20 kutengeneza chipsi.
Hivyo, walitumia jumla ya dakika 10 + 20 = <<10+20=30>>30 kupika.
Filamu hizo mbili zina muda wa jumla wa dakika 120 + 90 = <<120+90=210>>210.
Hivyo, Joseph na marafiki zake walitumia dakika 210 + 30 = <<210+30=240>>240 kutazama filamu na kupika.
Kwa saa, hii ni sawa na 240 / 60 = <<240/60=4>>4 saa.
