Answer:

The width of the waterway is determined by the number of piers constructed in the aqueduct. In this case, we are given that there are 6 piers, and we need to calculate the width of the waterway.

Given:
Width of the river = 111 m
Number of piers = 6

Calculation:

To determine the width of the waterway, we need to subtract the width of the piers from the total width of the river.

Step 1: Calculate the total width occupied by the piers.
Since there are 6 piers, each pier will occupy a certain width. We can calculate the width of each pier by dividing the total width of the river by the number of piers.
Width of each pier = Width of the river / Number of piers
Width of each pier = 111 m / 6
Width of each pier ≈ 18.5 m

Step 2: Calculate the width of the waterway.
To determine the width of the waterway, we subtract the total width occupied by the piers from the total width of the river.
Width of the waterway = Total width of the river - Total width occupied by the piers
Width of the waterway = 111 m - (Width of each pier * Number of piers)
Width of the waterway = 111 m - (18.5 m * 6)
Width of the waterway = 111 m - 111 m
Width of the waterway = 0 m

Explanation:

The width of the waterway is determined by subtracting the total width occupied by the piers from the total width of the river. In this case, since the width of each pier is approximately 18.5 m and there are 6 piers, the total width occupied by the piers is 18.5 m * 6 = 111 m. Therefore, the width of the waterway is 111 m - 111 m = 0 m.

Conclusion:

The width of the waterway will be 0 m, indicating that there is no space left for the water to flow through the aqueduct. This means that the aqueduct construction is blocking the entire width of the river, which is not feasible. Therefore, the aqueduct design needs to be revised to ensure a sufficient width for the waterway.
