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

### Instruction:
Miriam spent 30 minutes doing laundry, 15 minutes cleaning the bathroom, a certain amount of time cleaning her room, and 40 minutes doing homework. If she spent a total of two hours on these tasks, how long, in minutes, did she spend cleaning her room?

### Response:
 Kuna dakika 60 katika saa, hivyo saa 2 ni dakika 2*60 = <<2*60=120>>120.
Hivyo, alitumia dakika 120 kwenye kazi hizo 4.
Kutoka muda huo, tunaweza kutoa muda alioutumia kwenye kazi nyingine 3: 120 dakika - 30 dakika - 15 dakika - 40 dakika = <<120-30-15-40=35>>35 dakika.
