1/49=x^2 where x is the side of the square
1/49=(1/7)^2, so the side length of the square is 1/7
Let
be the time it takes for pumps A, B, and C (respectively) to fill 1 tank. Then

Now,

Then

This means

and

Working together, all 3 pumps would operate at a rate of

or 1 tank in 1 hour, so the answer is D.
