### Instruction:
 James hufanya kazi za nyumbani. Kuna vyumba 3, sebule 1, na bafu 2 za kusafisha. Kila chumba huchukua dakika 20 kusafisha. Sebule huchukua muda kama vyumba 3 pamoja. Bafu huchukua muda mara mbili ya sebule. Pia hufanya usafi wa nje ambao huchukua muda mara mbili ya kusafisha ndani. Anagawana kazi na ndugu zake 2 ambao ni haraka kama yeye. Anafanya kazi kwa muda gani, kwa saa?



### Response:
 Inachukua dakika 3*20=<<3*20=60>>60 kusafisha sebule.
Hivyo inachukua 60/60=<<60/60=1>>1 saa kusafisha sebule.
Bafu huchukua 2*1=<<2*1=2>>2 saa kusafisha.
Hivyo jumla, inachukua 1+1+2=<<1+1+2=4>>4 saa kusafisha ndani.
Nje inachukua 4*2=<<4*2=8>>8 saa kusafisha.
Hivyo jumla inachukua 4+8=<<4+8=12>>12 saa kusafisha kila kitu.
Anagawana kazi 1+2=<<1+2=3>>3 njia.
Hivyo kila mmoja wao anafanya kazi kwa saa 12/3=<<12/3=4>>4.
