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

### Instruction:
 Michael amekwama ndani ya lifti ambayo inaendelea polepole kushuka sakafu ya chini. Lifti inahitaji kushuka sakafu 20 ili kufika chini. Inachukua dakika 15 kwa lifti kusafiri nusu ya kwanza ya sakafu. Kisha inachukua dakika 5 kwa kila sakafu kushuka kwa sakafu 5 inayofuata. Kisha inachukua dakika 16 kwa kila sakafu kushuka kwa sakafu 5 za mwisho. Kwa saa, lifti ilichukua muda gani kufika chini?



### Response:
 Kwa sakafu 5, inachukua lifti dakika 5 * 5 dakika kwa sakafu = <<5*5=25>>25 dakika kushuka.
Kwa sakafu 5 za mwisho, inachukua lifti dakika 5 * 16 dakika kwa sakafu = <<5*16=80>>80 dakika kushuka.
Kwa kuwa inachukua dakika 15 kushuka nusu ya kwanza ya sakafu, na dakika 25, 80, na 15 kushuka sakafu tatu zilizobaki, inachukua dakika 15 + 25 + 80 = <<15+25+80=120>>120 dakika kushuka chini.
Kwa kuwa kuna dakika 60 katika saa, inachukua dakika 120 / dakika 60 kwa saa = <<120/60=2>>2 saa lifti kushuka chini.
