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

### Instruction:
 Muuguzi wa shule anapaswa kufanya ukaguzi wa kichwa kwa wanafunzi wa shule ya msingi. Anapaswa kukagua watoto 26 wa darasa la kwanza, watoto 19 wa darasa la pili, watoto 20 wa darasa la tatu, na watoto 25 wa darasa la nne. Ikiwa kila ukaguzi unachukua dakika 2, muuguzi atatumia muda gani kukamilisha ukaguzi wote?


### Response:
 Muuguzi anapaswa kukagua wanafunzi 26 + 19 + 20 + 25 = <<26+19+20+25=90>>90
Kila ukaguzi unachukua dakika 2 hivyo 90*2 = <<90*2=180>>180 dakika
180 dakika = 180/60 = <<180/60=3>>3 masaa
Muuguzi atatumia masaa 3 kukamilisha ukaguzi wote.
