If you pour 6 cups of water a day into a 100 gallon water tank how many days until its full

Question

JUST ANSWER

 

Answer 1

1 gal = 16 cups

 

(6 cups)/(16 cups/gal) = 3/8 gallons per day

 

Note:  This is less than half a gallon per day, thus it takes

more than 2 days to reach a gallon in the tank.  Simple logic

dictates your final answer better be more than 200 days ...

 

(100 gal)/(3/8 gal/day) = 100(8/3) = ______ days

Answer 2

To answer this, you must know how many gallons are represented by 6 cups.

 

Either your class has provided a conversion facts table, or you can Google to ask "how many cups make one gallon.:

 

Then you divide that # of gallons per day INTO 100 gallons, and that's how many days it would take.

(Assume tank is closed so there are no evaporation problems.)

 

Not a very efficient way to fill a tank!
