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

### Instruction:
Patricia has 4 barrels of 7 gallons each. All of them are empty, and there's only one faucet with a flow rate of 3.5 gallons per minute. How many minutes will it take to fill all 4 barrels?

### Response:
 Ikiwa Patricia ana mapipa 4 na kila pipa lina lita 7, basi jumla anahitaji lita 4*7=<<4*7=28>>28
Ikiwa bomba linaweza kutoa lita 3.5 kila dakika, basi atahitaji dakika 28/3.5=<<28/3.5=8>>8 kujaza mapipa yote 4
