### Instruction:
 Tangi la maji la Jacob linaweza kuhifadhi hadi lita 50 za maji. Jacob anakusanya maji kutoka mtoni na mvua ili kujaza tangi lake la maji. Anaweza kukusanya mililita 800 za maji kutoka mvua na mililita 1700 za maji kutoka mtoni kila siku. Jacob anahitaji siku ngapi kujaza tangi lake la maji?


### Response:
 Jacob anakusanya mililita 800+1700= <<800+1700=2500>>2500 za maji kutoka mvua na mtoni, mtawalia, kila siku.
Kwa kuwa lita 1 ni sawa na mililita 1000, basi lita 50 ni sawa na 50x1000= <<50*1000=50000>>50,000 mililita za maji.
Hivyo, Jacob anahitaji siku 50,000/2500= <<50000/2500=20>>20 kujaza tangi lake la maji.
