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

### Instruction:
Casey is pumping water out of her well. She can pump 3 gallons a minute. She has 4 rows of 15 corn plants each, and each plant needs half a gallon of water. She also has 10 pigs, which each need 4 gallons of water, and 20 ducks that each need a quarter of a gallon of water. How many minutes does Casey need to spend pumping water?

### Response:
 Kwanza tafuta idadi ya mimea ya mahindi: mimea 15/safu * safu 4 = <<15*4=60>>60 mimea
Kisha tafuta maji yanayohitajika kwa mimea ya mahindi: mimea 60 * nusu galoni/mmea = <<60*1/2=30>>30 galoni
Kisha tafuta maji yanayohitajika kwa nguruwe: nguruwe 10 * galoni 4/nguruwe = <<10*4=40>>40 galoni
Kisha tafuta maji yanayohitajika kwa bata: bata 20 * robo galoni/bata = <<20*1/4=5>>5 galoni
Sasa ongeza maji yanayohitajika kwa jumla: galoni 5 + galoni 40 + galoni 30 = <<5+40+30=75>>75 galoni
Hatimaye, gawanya maji yanayohitajika kwa kasi ya kusukuma ya Casey: galoni 75 / galoni 3/dakika = <<75/3=25>>25 dakika
