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

### Instruction:
It takes 1 hour for refrigerated dough to come to room temperature.  It takes 15 minutes to shape the dough and 2 hours to proof.  The bread takes 30 minutes to bake and 15 minutes to cool.  If the bakery opens at 6:00 am, what is the latest time the head baker can make it to the store to start working?

### Response:
 Inachukua saa 1 kuleta unga kwenye joto la kawaida na masaa 2 kuongeza unga, kwa hivyo ni 1+2 = <<1+2=3>>3 masaa.
Inachukua dakika 15 kuunda unga, dakika 30 kupika na dakika 15 nyingine kwa baridi, kwa jumla ya dakika 15+30+15 = <<15+30+15=60>>60.
Kuna dakika 60 katika saa 1, kwa hivyo inamchukua saa 1 zaidi.
Kwa jumla inachukua masaa 3+1 = <<3+1=4>>4 kutoka mwanzo hadi mwisho kuandaa mkate.
Ikiwa bafuni inafunguliwa saa 6:00 asubuhi na inachukua masaa 4 kuandaa, basi saa ya mwisho mkuu wa upishi anaweza kufika ni 6-4 = <<6-4=2>>2:00 asubuhi.
