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

### Instruction:
The American swallow can lift into the air and carry a maximum of 5 pounds of weight, while the European swallow can lift and carry twice the weight as the American swallow.  If there was a flock of 90 swallows, containing twice as many American as European swallows, what is the maximum combined weight the flock can carry?

### Response:
 Ikiwa kondoo wa Ulaya anaweza kubeba mara mbili ya uzito wa kondoo wa Marekani, basi kondoo wa Ulaya anaweza kubeba pauni 5*2=<<5*2=10>>10.
Ikiwa kuna kondoo wa Marekani mara mbili ya kondoo wa Ulaya, hiyo inamaanisha kuna kondoo wa Ulaya 90/3=<<90/3=30>>30.
Hivyo, kondoo 30 wa Ulaya wanaweza kubeba hadi pauni 30*10=<<30*10=300>>300.
Kwa kuwa kondoo wa Marekani wanaweza kubeba pauni 5 kila mmoja, hiyo inamaanisha kondoo 60 wa Marekani wanaweza kubeba hadi pauni 5*60=<<5*60=300>>300.
Hivyo, kundi la ndege 90, lenye kondoo 30 wa Ulaya na kondoo 60 wa Marekani, linaweza kubeba hadi pauni 300+300=600.
