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

### Instruction:
A hurricane is approaching the southern coast of Texas, and a rancher is planning to move 400 head of cattle 60 miles to higher ground to protect them from possible inland flooding that might occur.  His animal transport truck holds 20 head of cattle.  Traveling at 60 miles per hour, what is the total driving time, in hours, it will take to transport all of his cattle to higher ground?

### Response:
 Kwa kuzingatia uwezo mdogo wa gari lake la usafirishaji (ng'ombe 20), ng'ombe 400 watahitaji safari 400/20=<<400/20=20>>20 kwa kutumia gari lake la usafirishaji.
Kusafiri kwenda eneo hilo kwa kasi ya maili 60 kwa saa kwa umbali wa maili 60 itachukua 60/60=<<60/60=1>>1 saa kusafiri kwenda tu.
Kwa kuwa kila safari inahitaji kusafiri kwenda na kurudi kutoka eneo la uhamisho, kila safari kamili itachukua 2*1=<<2*1=2>>2 masaa.
Hivyo, safari kamili 20 zitachukua 20*2=<<20*2=40>>40 masaa ya muda wa kuendesha gari.
