### Instruction:
 Inachukua David dakika 10 kusafisha madirisha 4. Nyumba ya David ina madirisha 64. Itachukua dakika ngapi kwa David kusafisha madirisha yote?


### Response:
 Inachukua dakika 10 kusafisha madirisha 4 na yeye ana madirisha 64 hivyo inagawanyika katika vipande 64/4 = 16.
Inachukua dakika 10 kusafisha kipande kimoja cha madirisha na yeye ana vipande 16 hivyo itamchukua dakika 10*16 = <<10*16=160>>160 kusafisha madirisha yote.
