### Instruction:
 Kiti cha kutelemka kinafikisha wapanda mlima kutoka chini ya mlima hadi kilele cha mlima, na kisha kuwadondosha ili waweze kuteleza kurudi chini ya mlima. Ikiwa inamchukua mpanda mlima dakika 15 kusafiri kwa kiti cha kutelemka kutoka chini hadi kilele cha mlima, na kisha inamchukua dakika 5 kuteleza kurudi chini ya mlima, ni mara ngapi mtu anaweza kuteleza kurudi chini ya mlima kwa muda wa masaa 2?


### Response:
 Inachukua dakika 15+5=<<15+5=20>>20 kwa mpanda mlima kusafiri kwa kiti cha kutelemka hadi kilele cha mlima na kurudi chini.
Masaa 2 ni dakika 60*2=<<60*2=120>>120.
Hivyo, katika dakika 120, mpanda mlima anaweza kusafiri kwa kiti cha kutelemka hadi kilele cha mlima na kurudi 120/20=<<120/20=6>>6 mara.
