### Instruction:
 Billy na Tiffany wana mashindano ya kuona ni nani anaweza kukimbia maili nyingi zaidi kwa wiki. Jumapili, Jumatatu, na Jumanne, Billy anakimbia maili 1 kila siku na Tiffany anakimbia maili 2 kila siku. Jumatano, Alhamisi, na Ijumaa, Billy anakimbia maili 1 kila siku na Tiffany anakimbia 1/3 ya maili kila siku. Jumamosi, Tiffany anadhani atashinda na anachukua siku hiyo. Billy anapaswa kukimbia maili ngapi Jumamosi ili kufikia sawa na Tiffany?


### Response:
 Billy tayari amekimbia maili 6 kwa sababu 1 plus 1 plus 1 plus 1 plus 1 plus 1 inafanya 6.
Tiffany tayari amekimbia maili 7 kwa sababu 2 plus 2 plus 2 plus 1/3 plus 1/3 plus 1/3 inafanya <<2+2+2+1/3+1/3+1/3=7>>7.
Billy anapaswa kukimbia maili 1 ili kufikia sawa na Tiffany kwa sababu 7 minus 6 inafanya 1.
