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

### Instruction:
Richard can clean his room in 22 minutes. Cory takes 3 minutes more than Richard to clean her room while Blake can clean his room 4 minutes more quickly than Cory. If they have to clean their rooms twice a week, how many minutes do all three spend cleaning their rooms each week?

### Response:
 Cory anachukua dakika 22 + 3 = <<22+3=25>>25 kusafisha chumba chake.
Blake anachukua dakika 25 - 4 = <<25-4=21>>21 kusafisha chumba chake.
Wote watatu wanaweza kusafisha vyumba vyao kwa dakika 22 + 25 + 21 = <<22+25+21=68>>68 jumla.
Kwa wiki, wanatumia dakika 68 x 2 = <<68*2=136>>136 kusafisha vyumba vyao.
