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

### Instruction:
A water tank has a capacity of 4000 gallons. Mack connects a pipe to the tank that fills the tank with water at the rate of 10 gallons per hour. How long will it take to fill the tank to 3/4 of its capacity?

### Response:
 3/4 ya tangi la maji ni 3/4*4000 = <<3/4*4000=3000>>3000
Ikiwa bomba linajaza tangi na maji kwa kasi ya galoni 10 kwa saa, itachukua masaa 3000/10 = <<3000/10=300>>300 kujaza tangi hadi kufikia 3/4 ya uwezo wake.
