120 barrels x 12 quarts per barrel = 1440 total quarts
1440 quarts  /  11 quarts per hour  = 130.91 hours to fill all the barrels
1 day = 24 hours
130.91 hours  /  24 hours  = 5.45 days = 5.5 days
        
             
        
        
        
Answer:
Step-by-step explanation:
The answer is actually
Let:
S=1+2+3+4+5+6+7+8+9+n
We know the answer to the following infinite sum:
S2=1-1+1-1+1-1+1-1+1-1+1-1+1-....= - 1/2
We can therefore solve for this sum:
S3=1-2+3-4+5-6+7-8+9-....
We add them:
S3=      1-2+3-4+5-6+7-8...
S3=       +1-2+3-4+5-6+7-8...
         ________________
2S3=    1-1+1-1+1-1+1-1+1-....
Therefore:
2S3=S2=
 
        
             
        
        
        
D.
1 3/7 = 1.43
therefore from least to greatest it would need to be 
1.38,1.4,1.43
or in the question
1.38, 1.4, 1 3/7
Therefore the answer would be D.
Hope this helps!
